[Buy/Sell/Trade / Re: Turbo/PCE/Genesis/SNES RGB to Component Video (YPbPr) Mod Chip Now For Sale!!!]

Has this been confirmed to work with the NESRGB PCB? If not, I'm about to test it soon so I'll report back about that.

[Buy/Sell/Trade / Re: Turbo/PCE/Genesis/SNES RGB to Component Video (YPbPr) Mod Chip Now For Sale!!!]

Yep, I've heard about the native component mod for the SNES. I've tried it on a few diffent SNES variants but I always get washed out colors (yellows seem to be mainly affected).

Yeah, I've heard the complaint on yellows. I hoped someone by now that was a professional EE would design the best circuit amp for those signals, but as it stands only a generic circuit is available. I would like to know the results if you add's steve's circuit to one that has the right chip, do both mods and compare results from the same unit. I guess you're already suggesting Steve's will be better.

For the sake of it, I'll try to do a side by side comparison sometime. I might also add Ace's BA7230 based circuit to the mix.

Steve's PCB has it's own issue(s) actually. I've witnessed some distortion or an undesired green tint on the top of the screen. The effect can be minimized with a sync cleaner or by adjusting the Y pot on the PCB. That said, overall, Steve's circuit does a better job that the native SNES component IMO.

I've uploaded another video of the board in action, this time installed in a SNES...

That was a fun game, Wild Guns. One of the few imports I gained an affection for and enjoyed.

BTW, what model SNES do you have ?? Just FYI, did you know about the native YPbPr/Component support ? Only if the video encoder chip doesn't say S-RGB anywhere, though.

Looks good sensato . With your permission I would like to add your demo video to my website.

Sure! No problem about that.

I have just uploaded a video comparison for the RGB to YUV board (composite vs component).

TurboGrafx 16 composite vs component comparison ( YS I & II, Lords of Thunder)

Video was recorded using an XRGB Mini going to an Hauppauge! HDPVR2. I can't get the composite to look better with that setup. :/

Let me know what you think. I'm aware that the colors might be off a bit, I suck and adjusting them.

[Buy/Sell/Trade / Re: Turbo/PCE/Genesis/SNES RGB to Component Video (YPbPr) Mod Chip Now For Sale!!!]

Do Any CRT TVs work with this mod? The ones I have tried all have extremely faded colors and look horrible even with adjustments.

However, colors looks awesome on my plasma

The CRT I tried it on gives pretty good results actually. Also, my 2 LCDs show a green horizontal bar on top of the picture (in the overscan) with the mod, my CRT doesn't.

Hi guys,

I ran into a little issue with the component board on one of my monitor. I got distortion on top of the screen for white screens, as shown in this video:

Duo Component Mod White Screen Issue

I thought it could be related to the sync so I wired pin 44 of the HU6260 IC to an LM1881. This solved the issue so I thought it could be useful to some of you.

Has anyone else encountered a similar problem?

[Console Repair/Mod Center / Re: Testing Turbokon's RGB to Component PCB with various systems...]

Alright, I'll try that. Thanks! I guess that explains why I get colors on screens which have bright backgrounds? Could pull-up resistors work too?

[Buy/Sell/Trade / Re: Turbo/PCE/Genesis/SNES RGB to Component Video (YPbPr) Mod Chip Now For Sale!!!]

Could it be that you've got it in VGA mode and the game you're trying doesn't support it, so it's in some weird, confused 15K mode rather than staying in 31K mode?

I should actually be in 15K RGB mode. I've grounded only one of the mode select pins. I'll have to check which one I grounded because I thought any of the two would give the same result.

I've tested the mod with different games and I get black and whites screens with all of them.

In order to avoid further pollution of this topic (which is supposed to be about selling the PCBs ;)), I've created a new topic in the TG/PCE repair/mod section...

[Console Repair/Mod Center / Testing Turbokon's RGB to Component PCB with various systems...]

I recently purchased 3 RGB to YPbPr PCBs from Turbokon. I love the result of this PCB with the TG16, the Genny and the SNES. Thanks to the steve for designing this converter by the way! I'm thinking about testing it with even more systems.

Somebody asked me if I could mod his Dreamcast with a component video ouput because his setup doesn't have a VGA input. Loos like the timing is perfect for a first test: the Dreamcast.

I've recorded some video of Ikaruga booting in composite and in component. I've edited the video so that both sequences are synched side-by-side. Here is the result of the test:

Dreamcast RGB to Component Test

For the test, the PCB has 1k resistors on the RGB line (SNES & Genny revision of the PCB). I've tried adding 1K pots in series with the 1k resistors but I couldn't get this right. I also tried replacing the resistors with the 1k pots but it didn't work either. I've even tried adding 220uF caps on the Dreamcast's RGB signal but it didn't change a thing.

I'm pretty stuck there, with no more ideas on how to make this work. Anybody's input is welcomed.

[Buy/Sell/Trade / Re: Turbo/PCE/Genesis/SNES RGB to Component Video (YPbPr) Mod Chip Now For Sale!!!]

I've tried the component board with a Genesis and I must say that this PCB gives incredible results!

I don't know if it is of any interest to any of you here but I'm actually trying to hook up the component board to different systems. Right now, I'm trying to do it with a Dreamcast. No success so far. I get a picture, but the colors are off and washed out. I'll update when I get better results.

I will eventually also try this with a Saturn and an N64.

Hey sensato glad you finally installed the boards. As for the dreamcast, may just need different resistors value at rgb input side to counter offset voltage. What values I don't know, thesteve will need to chime in.

i would need to look at the signals on the DC
the resistors are to lower the RGB to match what the PCE puts out

I tried with 1K pots instead of the resistors and I can't seem to find anything that works. The screen is actually black and white most of the time (except for the Dreamcast boot screen which looks perfect). I plan to film everything to give a better idea of what's going on...

I could scope the Dreamcast's RGB signal but I wouldn't really know what to do with what I'll find.

[Buy/Sell/Trade / Re: Turbo/PCE/Genesis/SNES RGB to Component Video (YPbPr) Mod Chip Now For Sale!!!]

Don't N64 need an amplifier circuit because the RGB signals is weak?
Is there any noticeable difference using a RGB cable on SNES and Genesis and modding them both with this component board?
Is the pic quality is better using the component board compared to using the consoles' native RGB cable output?

Yeah, as far as I know, the N64's RGB does need to be amplified. The picture will be too dark if not amplified. there might be some models which do not need RGB amplification though, I'm not 100% sure about that.

I haven't done a side by side comparison but from what I've seen, I'd say that the component video quality with Turbokon's RGB to component PCB is as good as it gets. In the end, I believe that it all depends of what your setup is because the PCB will work only with a flat screen that has a component input that is 240p-compatible or a bulky CRT.

If you use an upscaler like the XRGB-3, I don't think there is any interest in converting the RGB signal to component before feeding it to the upscaler.

[Buy/Sell/Trade / Re: Turbo/PCE/Genesis/SNES RGB to Component Video (YPbPr) Mod Chip Now For Sale!!!]

Why bother with the Dreamcast?  Just get the VGA outbox and enjoy much better grafx.  Also the Saturn has RGB out already so just a Scart lead and a scart converter.

Somebody actually asked me to mod his Dreamcast with a component output because the TV he uses for gaming doesn't have a VGA input.

Also, some people prefer to have component right out of their systems instead of having to use an external RGB to component or HDMI converter/upscaler.

Besides, the PCE can rather easily be modded to output RGB and then be hooked to a converter/upscaler. Yet, people still find interest in the RGB to component mod...

I want to do an R-type ship like the one in Arkhan's pic and other ships from shooties like the soldier series and darius

That also is one of my favorite boss of all time. Too bad it's such an easy boss. I would have been even more memorable if it was tougher.

Great jobs on the bead arts guys. 16-bit bead arts look so damn good, like that Master Higgins.

[Console Repair/Mod Center / Re: Weird Duo problem (supply related?)]

Ok, I'll check that out.

If a trace is corroded/cut somewhere, I'll have a hard time finding it. I'm seing two crystals on top of the Duo PCB, I'll check their output and maybe try to replace them. I'll also check pin 10 of HU6280 and pin 2 of HU6260. which are supposed to be the clock for those ICs according to the PCE netlists found here: http://gamesx.com/wiki/doku.php?id=pcenetlist

What's the distinction between clock and crystal and how does this translate to the Duo?



This is what my Duo boot screen looks like:

[Console Repair/Mod Center / Weird Duo problem (supply related?)]

Hi guys,

I've got a Duo with a weird problem here. What happens is that it's an intermittent thing. Sometimes the unit powers on, but the audio is slowed down and the picture is black & white and all snowy/distorted. The laser seems to work fine in that case too (it checks to see if a CD is in when I push Start at the Duo boot screen).

Other times, when I turn the switch on, no picture or sound show up at all, and the laser doesn't work either.

I've tried the Duo with two different working AC adapter. I also did on full cap kit on the unit and it didn't fix anything. I am starting to think a trace might have been cut by a leaking cap somewhere but I have no idea where too look for it. I suspected it might be a VCC issue but both 7805 seem to output correct voltage. I've also checked most of the testpoints recommended here: https://www.pcengine-fx.com/forums/index.php?topic=7376.msg123430#msg123430. Everything seems ok.

I'm starting to run out of ideas but I am thinking about scoping the video IC of a working system and comparing it with the faulty system's one. Any other ideas? Thanks!
