[Console Repair/Mod Center / Re: Game-Tech region modded TG16 can't use everdrive]

The problem was terrible design of the TED v1's, both Kevtris and Rene of DB Elect. have said this.
The level translation on v1 TEDs was just resistors, v2 stuff used proper level translators.
I don't actually remember talking to you about this, but the tg16 region mod board never had any problems with even v1 TEDs....
I rarely get to this forum any more so email me direct if you still need help...

[General Gaming / Re: Hi-Def NES - a 1080p HDMI mod kit!]

Do those hd crt's have menu's and/or possibly a 'game mode' you can switch to?
I'd also try turning off edid on the kit.

[General Gaming / Re: Hi-Def NES - a 1080p HDMI mod kit!]

Pre-oders sale page is live, has been all day and looks to be holding up no problems so far.

Hi-Def NES update - kits ready for sale Sunday July 3rd

[Console Repair/Mod Center / Re: I reworked the region mod pcb for Turbo Duo - now it's super easy!]

Will this fit in a Turbo Express?

Haven't tried it yet as there is a switchless version that was meant for the portables, just never got around to making it yet. Anyway, will see about fitting this one in them and maybe find a hole for the switch that doesn't require cutting.

[Console Repair/Mod Center / Re: I reworked the region mod pcb for Turbo Duo - now it's super easy!]

The universal version is now done and for sale - http://www.game-tech.us/shop/

Vid of the testing of the boards I had fabbed and assembled by pcbway:

[General Gaming / Re: Hi-Def NES - a 1080p HDMI mod kit!]

Kevtris posted an update video last night:

Biggest news is the next batch of kits has been ordered!
There is also a small firmware update, v2.25.
http://blog.kevtris.org/blogfiles/HiDefNES%20Update%20V2.25%20final.nes
This fixes a few games and interpolation.

[Buy/Sell/Trade / Re: Turbo Grafx 16 / PC Engine / Express / GT Region Mod Chips for sale!]

right, this is a 2.4 board everdrive (dont know what bios)
didnt have to do anything to it, no pull-up/down or added caps

Well that's great! I'll get a hold of a newer TED and retest mine, hopefully it works!

[Buy/Sell/Trade / Re: Turbo Grafx 16 / PC Engine / Express / GT Region Mod Chips for sale!]

well i just tried a 2.4 in my modded express that refused to run in a DoujinDance modded DUO and it works perfect
also TurboKon tested the ED2.4 on a white PCE with the flex board (ver3)

Excellent! So 2.4 is the hardware version or OS or firmware? That could be the reason mine isn't working, it's a v1.1 board! That the TED I sent you for testing with my pcb on the CG and white pce.
So you didn't have to add the pull-downs or the bigger cap for it to work on the CG and white pce consoles, like you suggested on mine?

[Buy/Sell/Trade / Re: Turbo Grafx 16 / PC Engine / Express / GT Region Mod Chips for sale!]

actually we have tested with everdrive and have yet to have an issue
as far as influence this is what i was shooting for in the first place, but TurboKon wasnt comfortable with soldering such small parts
tho i could say they were both influenced by me

What version of the TED are you testing with? Maybe that's the difference...

[Buy/Sell/Trade / Re: Turbo Grafx 16 / PC Engine / Express / GT Region Mod Chips for sale!]

So the obey chip version 2 is just about out.  Fear not, we are working on a newer smaller form factor version that will cut down on installation time.  The new obey chip will install and solder on the hucard slot 9 pins.  Best of all, it will work on all turbografx and pce systems including the turbo express and pce gt.  Unlike previous versions of the obey chip, the main and switchless chip will be on one board.

Did my design influence the v3?
Also did you test the TED at all? The only reason I haven't released my boards was because thesteve never figured out how to get the TED to work in the coregrafx consoles, or never told me if he did...

[General Gaming / Re: Hi-Def NES - a 1080p HDMI mod kit!]

Kevtris posted an update to the hi-def's firmware, only 30-40 consoles are out there right now so this mostly just applies to them:

Weeeelllll, here it is. I received the everdrive yesterday and loaded V12? firmware onto it (the version before the "fix" for the HDMI adapter). Thinking this was going to be a "worst case" test. It worked perfectly with the games I tested- I tested about 6 or 7 different mappers and all is well. Reset even worked properly. Before, the error messages wouldn't show up properly but they do now (i.e. no SD card).

FDS is working properly now, and so do MMC5 games (i.e. reset works there too, and no need to use a game genie). I sent it out to a couple people and they could apply it properly, though one person has problems.

He was using a powerpak, and his MMC3 file was different than mine- I think he has the savestate mappers. This caused the update to not work. It reported a data corrupt error and refused to flash the firmware. I gave him my mapper 4 file direct off the CF card on my powerpak and then he got it to work properly.

I don't know anything about the save state mapper, but I assume it cannot load 512K PRG ROMs, because it uses some of the RAM for the savestate part? I could be totally wrong but that's just my first guess.

It works on some everdrives, but some people had issues.

Anyways, here is the update:

http://blog.kevtris.org/blogfiles/HiDefNES%20Update%20V2.00.nes

To use it, load this ROM on a flash cart (or burn EPROMs? hehe), run it and then get into the Hi Def menu, select "save and update", then "update firmware", and follow the on screen prompts. It will check the update for integrity, and then flash it if it passes the check. Cycle power and it will use the new firmware.

[General Gaming / Re: Hi-Def NES - a 1080p HDMI mod kit!]

I think Kevin is more focused on firmware/compatibility updates than ordering kits, but I know he was close to done with both just haven't heard either way from him.

[General Gaming / Re: Hi-Def NES - a 1080p HDMI mod kit!]

From Twitter:

@krikzz #EverDrive N8 OS v13. Now compatible with NES HDMI adapter!
krikzz.com/forum/index.ph...

Excellent! Thanks for the update, will spread the word!

[Buy/Sell/Trade / Re: Easy region mod pcb for the TG-16 console!]

I had them assembled, costs more, but end up with much nicer product. Being only 2 components they could have been done by hand, but I wanted to try having the fab do it and I think it was worth it.

[Buy/Sell/Trade / Re: Easy region mod pcb for the TG-16 console!]

Neat board for sure.  Unfortunate that it costs nearly 70% more than the last boards we made.  I guess it includes a switch.

Yeah $10 more to save a lot of time and effort. Most of that was fab and assembly costs...
BTW how did you test each board you sold?

[Buy/Sell/Trade / Easy region mod pcb for the TG-16 console!]

I've been working on it a long time, but it's finally ready for sale!
This is thesteve's region mod circuit on a pcb I designed to make it super easy to install on the US tg16 console, does not work on any other NEC console, does not work on the PAL tg16.
It's as easy as solder down, cut the 8 pcb traces, run 3 wires to a switch, and mount the switch somewhere on the console shell.

http://www.game-tech.us/store/

There is an option to buy the kit with wire and switch or pcb only in the little drop down box.
Shipping is only set up for US and Canada, but that should be the only countries interested in this kit.
I only have pri mail for US and economy for Canada for now.

Finally some progress on the tg-16 region mod pcb!

[General Gaming / Re: Hi-Def NES - a 1080p HDMI mod kit!]

There was a vrc7 mapper released for the NES Everdrive. This means Lagrange Point can be played!
I had some trouble getting a couple of the roms to work, english translation worked 2 times and not once since...
The hi-def nes kit shines here as it's the only way to get the expansion audio to work since the kit generates it internally, no need for the exp audio part of the mapper pack to work, which currently does not.
It was also my first attempt at audio capture via line out or headphone jack of the projector and tv, neither work very well.
Can anybody recommend a good hdmi 1080p capture card?

[General Gaming / Re: Hi-Def NES - a 1080p HDMI mod kit!]

Initial stages of fitment of kit to front loader NES.

[General Gaming / Re: Hi-Def NES - a 1080p HDMI mod kit!]

Thats cool, but you need a better selection then that for audio comparison. Try to put something together and get back with us on it.

I'll see if he can do some other game captures. Might even try to get a 1080p capture card.
Did the smb2 vid sound good to you?

[General Gaming / Re: Hi-Def NES - a 1080p HDMI mod kit!]

I just remembered Kevin's first vid was a capture, mostly to show it working in 720p, but it prolly has a better audio track than i'll get with my equipment.

[General Gaming / Re: Hi-Def NES - a 1080p HDMI mod kit!]

Yeah i'm not sure what the best way is to do a sound comparison. I doubt I have the proper equipment. If I just did it with what I have, I doubt it would be quality enough for ppl that could really distinguish between them if there was anything to hear. Any ideas?

[General Gaming / Re: Hi-Def NES - a 1080p HDMI mod kit!]

I know it's not a nintendo forum, but I love this forum, been coming here for 12 plus years, but I did post this in pcengine-fx.com » Non-NEC Console Related Discussion » Console Chat...
Plus it's more of a review of the Hi-Def kit so I didn't see a problem posting about it.

[General Gaming / Re: Hi-Def NES - a 1080p HDMI mod kit!]

Some of the Analogue NT's have made it out to customers.
Here's a link to one guy's review of it with the Hi-Def kit installed:
http://filthypants.blogspot.com/2015/08/analogue-nt-hdmi-first-look.html

[General Gaming / Re: Hi-Def NES - a 1080p HDMI mod kit!]

Somethings I want to know, because evidently I missed this initially:

Does this upgrade completely replace the audio coming out of the cpu? As in, does it take over handling of the audio, and emulates it?

Per what you stated prior:

Built in overclocking with option to not have it mess up the sound pitch.


All audio is generated in the kit, so it will be %100 digital and theoretically noise free.
User will be able to control each audio channel from the menu.
You will be able to adjust left and right volume output of each channel independently.
Most expansion audio chips will also be programmed in to the kit and we hope to auto detect which one will be needed for a game that is being played, but may also have the option to turn each on and off.
Currently working: normal nes audio, fds, N106, mmc5, and sunsoft 5B.
VRC7 is still a maybe...
5.1 and 7.1 is also a maybe...

So if the audio is just emulated, how close to the original does it sound? And how will this work with games like Akumajo Densetsu?

Concerning the PPU side of things:

Aspect ratio will be user adjustable in the menu, seen as horizontal stretch in the menu in the vid.

A few palettes will be included and user selectable in the menu.
Custom palettes can be uploaded to the nesHD using a flash cart etc.

Scanlines will be included....

Is the original PPU actually doing anything in the end result, or is this upgrade being put in between the PPU and pcb, and does it just take over the image processing side of things? I ask this due to reading your statement concerning the new color pallet and scan-line options and all.

IF so, this basically means the visual side is being emulated by new hardware, correct, not just upscaling the original composite signal generated by the PPU? So what exactly does the kit need the old PPU for?

This brings me to the whole emulation aspect of it all. If this thing is just replacing the original audio with emulated audio, and replacing the ppu generated composite with a new emulated image with scan-line and color palette options, what makes the end result any different then using something like a Retron 5 clone system, or something like this:

http://www.ebay.com/itm/DIY-Famicom-2-game-machine-Outputs-VGA-RGB-S-VIDEO-AV-With-scanlines-/271948293299?hash=item3f5161a4b3

I mean, if your not using the original audio or video signal anymore for anything, then the core of the system has basically been turned into a clone system, other then a Nintendo made PCB, system shell, and gamepads. I know it sounds dirty to put it like that, but when you state its not a clone, but then go about replacing original aspects of the hardware with emulated ones, basically that is cloning to achieve a end result.

Part of what made the Nes/Famicom special was that unique sound and look generated by the original cpu and ppu, so why would I want to replace this? Pretend I am a potential customer and convince me as to why your product would be the better replacement, as opposed to a Retron 5, the pcb in the auction, or just going with something like the NESRGB kit.

I initially thought this was just some upscaler pcb that was going to act like a cheap upscaler option, taking the composite video and cleaning it up some and upscaling it while using the original audio as an audio source, but evidently I was way off in thinking that. I should have read the initial postings about this upgrade.

Kevtris isn't a member here and can't even see these post so I asked him to reply:

I "digitally recreate" the sound because I have to make a digital version of it for HDMI.  The only other option would be to do audio capture, but that is lame because it would introduce noise.   the decision to "digitally recreate" the audio was not taken lightly, and produces the best end result.

The PPU is rendering 100% of the video.  The hi-def nes captures the digital video on the PPU's EXP pins.  The other things (scalers, scanlines) are just added on after capturing the video because I can.   I have to "lie" to the PPU to turn on the EXP pins and change the palette going to the chip so that the video pin can be used to capture the 5th palette entry bit.

You can watch the video coming out of the PPU to see how this works.  the sprites will be white and the background black.    The RGBNES board works in a very similar manner.  I think it uses white and grey, though.  It also extracts the video in the same manner I do.

The NES CPU is still rendering the audio, you can listen in if you like.  The benefit of regenerating it digitally is cleaner audio, and if you overclock the CPU, the audio pitch won't change (you can turn this on/off).  If you listen to the analog audio during overclocking, the pitch will shift.

Since the NES CPU is still running the game code, and the NES PPU is still rendering ALL the video (the HDN does not render video) then it isn't a clone system.  Adding audio rendering to the FPGA simply was required to get the highest quality HDMI possible.    If you remove the CPU or PPU, the device will no longer work.   If it was a "clone system" it should be possible to remove either or both chips and have the system continue to function.  This of course is not the case.

End quote.

I believe the retron 5 has been proven to be an android OS running emulators, in fact I think several of the emulators allegedly infringe on the rights of multiple emulator authors:
http://www.nintendolife.com/news/2014/09/hyperkins_retron_5_console_allegedly_infringes_on_the_rights_of_multiple_emulator_authors
I never heard if there was any resolution of this issue though...

It does appear that famicom kit has a UMC cpu clone chip, which we also tested a cpu/ppu pair on the hi-def and they worked like originals. I pulled them from a brazillian clone I have. The video looks to be recreated on a fpga.

Also, the kit will do all expansion audio chips without there even being original exp audio chips/circuits present, only the mapper needs to be on the cart, but you do have to turn them on in the hi-def's menu. CV3 uses vrc6 swap, and iirc it's the only game that does, but it's there!

[General Gaming / Re: Hi-Def NES - a 1080p HDMI mod kit!]

Kevin's post from the nesdev thread:

Well, Jason (gametech) came over tonight and we did a bunch of everdrive testing. Turns out his everdrive works fine on my HDMI modified toploader. We ran SMB3, Zelda, Double Dragon, Faxanadu, SMB, SMB2, and a bunch of other games and all of them seem to work fine. Overall I tested NROM, UNROM, MMC1, and MMC3 games.

The only minor issue I had was reset. sometimes I had to mash reset a few times before the menu would come back up. Once (out of 15-20 games run) I had to cycle the power.

This confirms what I said earlier about the ED working back in november. It seemed to work then and still seems to work now.

Turns out his ED is one of the very first made, and as such it has really old firmware on it. Rev 3 firmware.


I also have a "modern" ED that uses the latest firmware. This ED does NOT work on the Hidef nes. The menu sometimes comes up and the graphics are always corrupt- looks like uninitialized VRAM. You can tell the menu is there, but you can't start a game, it just resets. Sometimes it's showing an error screen I think, but you can't read it. I did not get this version to run a game.

So I took the rev 3 firmware off Jason's ED and put it on the "modern" ED, and guess what it worked just as well as his ED did! So whatever change happened between rev 3 and 4 of the ED firmware seems to be the reason. I put the latest version of firmware on Jason's ED and it failed in the same way the "modern" ED failed.

These are good data points on tracking down the problem I think.

I was thinking of making a video showing this happening.

Regarding the HDMI connector fit, I test fitted my toploader with the cable I have here and it worked OK so I thought it was going to be fine. The connector is recessed as far as it is so I could use the same board on the NES and the nt both. I tested so I thought it was OK, but turns out it isn't. Various cables seem to have different "tongue" lengths. I modified one by cutting some of the plastic off with an xacto knife and it only took me about a minute to do this. I was surprised how easy it was actually.

This board would work fine on a front loader I think. the plastic is much thinner on the back so the fit should not be an issue there.

On the next run I will move the connector out on a little PCB "flag" to fix this issue.

Like any other brand new high complexity product, there's going to be some things to fix. There's literally hundreds or even thousands of little things that could go wrong, so it's not unlikely one or two of these things will slip through. I tried to do extremely thorough testing here. This included 20 sets of CPU/PPU's, 4 different NES main boards (front loaders and top loaders), 12 or 13 Hidef NES proto boards I hand stuffed and reflowed, and 10 different monitors. There is also the HDMI Analyzer that I paid quite a lot of money for just specifically so I could debug the HDMI link on this project. Overall I am in fairly deep on this project financially so I hope it will eventually pay off, and that I will make a bit more than minimum wage for the hours I put in and the cash I spent for tools and prototypes. Overall 5 or 6 people were helping me test/debug it (it wasn't just 2 people as someone claimed).

Not a whine or anything, just stating what the facts are. Hope this clears up some of the loose ends people have about the project. I hope to be able to supply as many boards as the modding community can use. There's not going to be any limit. So long as people buy them I will sell them, barring any parts availability issues.

[General Gaming / Re: Hi-Def NES - a 1080p HDMI mod kit!]

The kit can output HDMI and RGB correct?

HDMI and DVI only.

[General Gaming / Re: Hi-Def NES - a 1080p HDMI mod kit!]

I had a couple issues on the first av fami install, but I think we got it figured out!

[General Gaming / Re: Hi-Def NES - a 1080p HDMI mod kit!]

You know Game-Tech.US, I really want to ask, because I remember dropping you a pm prior about one of your region mod pcbs and you not wanting to sell it or whatever, do you even actually sell any of the stuff you guys come up with? Or do you just come on to forums and try to get attention about it so you can use the free advertising to sell your premodded systems & mod work only?

Because honestly this doesn't feel like an effort being made to help any given community, here or elsewhere. It just comes off as a giant push towards lining ones wallet, both yours and the guys at Analogue Nt. I mean seriously, ebay and $300 minimum bids? Totally disgusting. If I had known this was your end game, the way you planned to release this shit, I'd have simply said fuck off from jump street and stopped paying any kind of attention to this. Total fucking waste of time.

Yup region mod pcb are still coming, in fact the tg-16 only version, the one that worked fine with the TED from the start, should be for sale soon. When I get time to make a vid about it i'll post it.
The duo/r/x version seems to work fine with the TED in US and JP duo/r/x's, but still not in the white pce or coregrafx so it was once again recently sent to thesteve to see if he could uncover a fix, if not it will prolly still be sold as for use with duo and duo-r/x only or not with TED on other consoles. I just keep wondering if ppl will even want it for pce systems since system cards are about the only thing the TED won't do so why bother trying to make it work on jp consoles?

Oh and the NT 'partnership' had nothing to do with me, in fact I wasn't told about it till everyone else already knew as well.
Already explained the $300 start bid reasoning as well, scroll back up to see that.

[General Gaming / Re: Hi-Def NES - a 1080p HDMI mod kit!]

You're right it is a fundraiser for getting more kits ordered. Other than that we really haven't deviated from the original plan of me doing a bunch of installs until kinks were worked out. I always did plan on selling my modded consoles on ebay just like I always have, but yeah why not do auction and let them bring in as much as possible? Also as stated in the vids $300 is about what it will cost ppl to get a modded top loader anyway since they usually sell for around $100 depending on condition and these are all excellent to mint, the kit is prolly gonna be $120 and installation $50 plus, and I still pay %15 to ebay off the top. The money from the auctions will get more kits ordered so we can better fill initial demand, only selling 50 will irritate ppl too and we agreed not to do preorders as there's always problems there as well. On top of all this we aren't even ready to sell kits even if we were just going to sell the 50 or so we have now. I took a ton of pics last night during the last install so we'd have some to go with the installation instructions that haven't been written up yet. The template for making the hole needs to be worked out and lastly we will get a web page set up with a shopping cart system so no one is trying to send us money when no kits are left etc.

[General Gaming / Re: Hi-Def NES - a 1080p HDMI mod kit!]

This vid is a run through of the menu and some features and some game-play on a 120" 1080p projection setup.

[General Gaming / Re: Hi-Def NES - a 1080p HDMI mod kit!]

Yeah you have to figure a top loader is about $100 depending on condition and these are all excellent or better since i'm harsher about judging these than most ppl since i've had so many. $120 for the kit and another $50 plus for instal, so yeah $300 start bid...

[General Gaming / Re: Hi-Def NES - a 1080p HDMI mod kit!]

Ok the first 6 Hi-Def NES modded US top loaders are up for auction on ebay, just search nes hdmi.
They were a bit late as I had a hell of a time uploading them because ebay wouldn't let me upload them and they weren't specific enough about why so I had to try several times. Turns out you can use the word 'mod' in the title, but if you say kit they think it has bundled accessories and if you are listing in the consoles category and don't have the bundled accs option listed then it won't upload. I was doing this from misterlister or whatever that shitty prog is named now. Then they marked them as duplicates even though I used different pics for top and bottom shots on each auction and some different txt in description. I had to add the 3 numbers of the serial number to the title to get them to release all the auctions as not dupes, FK!!!

[General Gaming / Re: Hi-Def NES - a 1080p HDMI mod kit!]

Yeah the Hi-Def kit is an option in the NT.

[General Gaming / Re: Hi-Def NES - a 1080p HDMI mod kit!]

We have the first batch of kits now, but are not planning to sell any just yet so be patient, watch these vids for more info:
First look at kits and lots of talk with Kevtris:

[General Gaming / Re: Hi-Def NES - a 1080p HDMI mod kit!]

Kevin's latest update:
Ooooh yeah. PCBs have arrived!

It won't be long now!

////////////////////////

I have already had an email asking if this means it's time to ship their console to me!?!? LOL NO!
I know you all are very excited to get this done, but my request of 'please don't email us and bug us about this until concrete plans are put out there' is still in effect, sorry...
Kevin is close on his end, but he will only have 100 kits and we haven't decided how to sell them just yet. Not to mention they aren't really done yet and I don't have any in my possession yet. Nor do I want a bunch consoles to show up at my house waiting to be modded...

[General Gaming / Re: Hi-Def NES - a 1080p HDMI mod kit!]

Latest update from Kevtris:

Woot, I finally sent the stuff off so the HiDefNES boards are in production! I have also posted the final "pre production" update. I don't know how long it will be until I get boards in hand but I will probably post another update video when that happens.

[General Gaming / Re: Hi-Def NES - a 1080p HDMI mod kit!]

For those that didn't see it here is the analogue NT running the hi-def kit scrolling through menu options:

[General Gaming / Re: Hi-Def NES - a 1080p HDMI mod kit!]

New vid from Kevtris:

Update #8 is now posted. This time I show how I place the parts and reflow solder it in a modified toaster oven.

After a few more minor additions, I think it will be ready for the world.

[General Gaming / Re: Hi-Def NES - a 1080p HDMI mod kit!]

Here's update #7 from Kevtris:
This time I totally redo the board layout, and I took a time lapse video of me doing this. You can watch the board "grow" from nothing to completion!

CopyNES USB was added, a 5V buck regulator on-board, and a form-factor re-do so it will properly fit the toploader.

Enjoy!

[General Gaming / Re: Hi-Def NES - a 1080p HDMI mod kit!]

Update #6 is now posted.

Looks like I'm about done on the software side. The things left:

* copynes
* updating via cart
* audio register viewer
* PCB redesign to fit in the toploader under the main PCB   

[Console Repair/Mod Center / Re: I reworked the region mod pcb for Turbo Duo - now it's super easy!]

[General Gaming / Re: Hi-Def NES - a 1080p HDMI mod kit!]

Latest update vid from Kevin:

Update #5 has been posted. The brightness on the HDMI output is a bit blown out but this is because of the capture card. I didn't spot it until it was rendered and posted. bleh. Every time I capture something it seems to screw it up in a different way.

Anyways, I show a couple games (Duck Maze, Orb 3D, and Micromachines) which apparently gave the nesRGB fits. Also, the flowing palette demo apparently doesn't work either. All four of these are shown.

Enjoy!
