[PC/Console/Mobile Ports / Re: Generic Hello World HuC source code?]

AWESOME!  That was perfect!  This is just what I needed!  Thanks a million!

[PC/Console/Mobile Ports / Generic Hello World HuC source code?]

Does anyone have any generic "Hello World" HuC source code?

I have been trying to compile something generic that works under any of the PCE emulators using the HuC compiler, but I have never seen source code for any type of demo program - all the demos no longer exist anywhere that I can find, or are now commercial applications and the source code is no longer available.

Something simple in C that generates a running executable for the PCEngine, options to have the output be either a cartridge, CD-ROM or Super CD-ROM, and allows you to use the C library included with HuC...

[PCE/TG-16|CD/SGX Discussion / Re: PCE Flash Cards]

Mmmm, was another issue with mine then.  The drivers were there and correctly named.  WinXP would not recognize the .INF file itself as valid.  I had to hand create the registry entries to install the drivers for it.

[PCE/TG-16|CD/SGX Discussion / Re: How old is your Turbo/Duo?]

Actually after looking at the Duo again, its got no date on the bottom, but the boards inside are dated 88.

[PCE/TG-16|CD/SGX Discussion / Re: How old is your Turbo/Duo?]

88 Japanese Duo, dont know about my US TG16 - have to take a look.

[PCE/TG-16|CD/SGX Discussion / Re: Map of Turbo Game Stores]

There used to be a pawn shop around here in Ft. Lauderdale FL that specialized in retro game systems.  They were pretty good and super picky - had to have everything for them to buy a system from you, and it all had to be in near perfect shape.  I will see if I can track them down again, but its been a few years.

As for New York, you can MAYBE find some in China Town in Manhattan itself - look for the ChinaTown Tech mall and go in there where they have the Chinese versions of the Anime videos and models - you might find them in there - they USED to have them there years ago.

Also out on Long Island, I found shops inside flea markets or open markets selling TG stuff - but that was years ago - I dont know if you will find any anymore.

[PCE/TG-16|CD/SGX Discussion / Re: PCE Flash Cards]

What they don't tell you is that the CD contains drivers for 639 other flash cart/USB setups so you get the fun task of trial and error. To top it all off, the driver itself is incorrectly named (at least on the CD I got). I had to rename it for it to work with the provided .INF.

Hi!  What did you have to rename exactly?  A file?  A line in the .INF file?  And what did you change - from what to what?  Thanks in advance!

Personally, I had to hack my registry to make a registry based manual install of the drivers for the SL4 to get it to work - the .INF file way never worked for me with WinXP SP2 and full current patches.

The only other caveat I would say to people is to use a fully wall plug powered USB hub with the NEO units, otherwise, if the port on your computer cannot provide the voltage and current the NEO unit wants during writing (it varies it during the write process) your unit will hang.  Having a guaranteed full voltage/current from a fully plug powered hub makes it work like a charm.

[Console Repair/Mod Center / Re: Do any NEC systems (FX included) have a CD drive with pins similar to IDE?]

If I remember correctly the CD drives in the PCE/TG16 units are modified mini-SCSI interface drives.  From what I remember there used to be an Apple hard drive interface years ago that was nearly pin for pin compatible, and with minor mods could be used with a patch cable hooked up directly to the unit.

[Buy/Sell/Trade / Re: Interest Check- new manufacture DUO replacement AC adapters]

Cool idea...  My original wall wart is working just fine, but I would buy a spare or two - always handy to have.  What I would like to see though is a 3rd party replacement for the CD-ROM unit for the TG16...

[Buy/Sell/Trade / Re: The COLOSSAL Sale: 841 games for sale]

Waiting for the re-count and updates...  What a great list!  I wonder if anything I saw I liked will still be left later on?

[Console Repair/Mod Center / Re: Play Japanese System Cards in TG16 CD unit?]

Definitely go with D-Lite's modifications - if you dont want to do it yourself, find someone who can use the soldering practice to do it for you. Pick yourself up an Arcade Card Pro.  The AC Pro works on almost every system out there, so go for it.  I can use mine with my TG-16 CD system by plugging it into my Purple Barney converter.  I can also plug it right into my PCE Duo and run Arcade games on that as well.

[Console Repair/Mod Center / Re: TURBO DUO SOUND FIX!! (56k beware)]

As many of you already know, I had recently gotten a PCE Duo that the CD sound and the ADPCM sound was not working.  Over the weekend I did a ton of capacitor replacement work on the board.

Day 1: When trying to open the unit to take stock about what capacitors I would need to get, after I unscrewed the main cover, a capacitor literally rolled out of the case when I turned the unit upright to remove the top cover.  I knew I was in trouble then!  But I was also taking this as a good sign that replacing capacitors would be a good thing at this point...  Never seen that before - a capacitor rolling out of a unit... 

I took stock of the capacitors that I would need, and went to the local Radio Shack.  I had to settle for a mixed bag for the type of capacitors - radial, non, polarized and non. 

I took it slow and replaced the capacitors one by one in the area marked in many previous pictures as the audio amplifier area - and the capacitor that fell off - a 47uf cap near the front of the unit.  I would literally replace one capacitor, then screw things back together and test to see if anything happened - good or bad.  Unfortunately, I only had one 22uf cap and really needed more of those.  I just took the time to replace some other caps in the nearby region of the audio amplifier area.  I found that almost every cap I replaced had either gunky or power residue on the circuit board underneath everything.  Another thing I found out - most of the 47uf and 22uf caps were counterfeit caps - probably why they failed and also dried out so badly.  At the end of the first day, I had replaced all but 4 caps in the direct audio area, and really needed at least one 22uf cap to complete that area's replacements. 

Day 2: Back to Radio Shack - this one was much better stocked, and I was able to get a bunch of 22uf caps and also get a few more space saving versions of some of the other caps.    My first job - finishing the replacement of the 4 remaining caps in the audio amp area.  It was not until I replaced the very last cap in that area, a 47uf cap just above the 22uf cap that a previous poster changed that gave them their CD audio back, that the CD audio returned for me.  That was great!    Now I was even more determined than ever - I wanted the ADPCM sound too!  I replaced all of the 22uf and 47uf caps on the board, replaced the caps next to and nearby the Oki chips on the board, and replaced a few of the larger caps by the headphone output area (I left the smaller 4.7uf caps in place - they seemed to be working).  In the end, I replaced over 20 caps on the board.  But no ADPCM sound... 

Day 3: I thought this was good enough for the moment. I only had 6 major caps and a dozen or so tiny minor caps to replace to actually finish a complete replacement.  I decided to give one final thing a try - to leave it running for several hours and then see what happens.  I left it on overnight, and the next morning gave it a try.  Sure enough, Madou Monogatari did not freeze up in the dungeon anymore, and the special sound effects came out! 

So in the end - one weekend's worth of cap replacements and testing is a complete success!  I have a totally working PCE Duo! 

Many thanks to all who came before me and shared their experiences too!

My own guess: I think it was the two 47uf caps near the front of the board that I replaced that did the trick for the ADPCM sound.  Replacing one probably made a nearby crystal start to work properly, and the other probably finally provided the right ground needed for the components in that area - and I think the ADPCM requests filter through one or more of the chips in that area.

[Console Repair/Mod Center / Re: No CD Sound on PCE Duo]

Awesome!  Thanks!  I'll have to do this over the weekend and see if I can get everything working!

[Console Repair/Mod Center / Re: Can I replace a laser on my CD rom unit?]

This is the same thing that is happening to me, but I was thinking it is the motor and not the laser unit that is bad.  Am I thinking wrong?  If the laser unit is bad, will the motor not turn?

[Console Repair/Mod Center / Re: TurboDUO mod needed- can anyone help?]

Board member D-Lite has a website dedicated to PCE mods and has a board he can sell you, or you can send your unit to him to do the mods for you.

Look to the left where it says "New!! PCE Region Mods!"

[Console Repair/Mod Center / Replacing TG-16 CD motor]

Before I start pulling wires and stuff, after doing some intensive tests on my TG-16 CD drive, I have found that the problem seems to be with the motor in my unit.  All the gears seem to be fine, and everything else is greased and working good for the internal bearnings and whatnot, and the electronics seem to be working okay too.  When I try to fire up the CD unit to play something, the motor gets a brief power kick to kick it over, but its not enough to make it run.

Any suggestions from anyone who may have worked on their own CD motor before, or knows about these motors, for what I should do next, and if I should replace it, if they have a suggestion for getting a matching motor.

Thanks in advance!

[Console Repair/Mod Center / No CD Sound on PCE Duo]

Hi!  I just recently got a PCE Duo for a great price in excellent condition - but the one problem with it is that any of the audio coming from the CD part does not play.  Non-CD based music and sounds come out - its totally fine when I play a Hu-Card based game.  When I play an audio CD, the Left/Right channel info shows up fine so I can see that at least at the low level, the audio IS being read from the CD, and CD based games all work, but with either no or minimal sounds.

I have read something about heat sinks causing some sound problems in the original Duo's - does anyone have any direct references about this or know exactly what should be replaced?

[Buy/Sell/Trade / Re: Turbo/PCE Flash Cart SPECIAL]

Definitely interested in two of the 64Mb ones or one of the 128Mb ones...  would love to get two of the 128mb ones but too short on cash...

[Console Repair/Mod Center / Re: My turbo grafx original cd player doesn't spin.]

Awesome.  Thanks you two!

[Console Repair/Mod Center / Re: My turbo grafx original cd player doesn't spin.]

Beyond that, keep an eye on for sale forum here. Also, subscribe to the Turbo List.

Has The Turbo List changed it's homepage and signup email?  I tried to sign up with no return responses yet, and tried to go to the home page here http://joyce.eng.yale.edu/~bt/turbo/ but the site is down.

[Console Repair/Mod Center / Re: My turbo grafx original cd player doesn't spin.]

Then you're getting ripped off.

A complete TG-CD console (core, CD-ROM, interface, controller, Sys 2 card) should run you in the $100 ballpark.

A CD-ROM alone should be much, much less.

Places / websites / whatever where you see those prices please.

[Console Repair/Mod Center / Re: My turbo grafx original cd player doesn't spin.]

Honestly, I'd always rather use NEC parts for a project like this, and for the relatively low price for a PC Engine CD-ROM unit ($50-60 last time I checked) and the little labor involved, I think I'm gonna go with the second choice.

If you know where to buy the units - especially at those prices, I am all ears.  I cant find a shop that repairs these at all anymore (they charged $60 to REPAIR them when they did so!), and the only units I find for sale are on eBay as part of the total units for several hundred.

[Console Repair/Mod Center / Re: My turbo grafx original cd player doesn't spin.]

This is the exact same problem I am having with my TG16 CD unit.  What do I lubricate inside and what do I lubricate it with?  I dont want to use the wrong type of lubricant or get it where it does not belong.  I have not looked for screws either - is there anything special I should be wary of when trying to open the unit?
