NESRGB board available now

[ckong]

I have posted all the orders. Now working on producing the next batch...

That is good news. Is it possible to make a reservation list for the guys who were out of luck with the first batch?

I fully support this idea.

I've just received my package from Tim!
Super fast shipping and well packaged!



NESRGB board, regulator with sockets and AV Famicom adapter board!


Weekend saved!

[frsj8112]

I've done a quick installation just to see if I could make it work





Many thanks Viletim for an amazing product!!

Nice thanks for showing off the palette switch.. mine couldn't come soon enough!

[leonk]

WOW.. the NESRGB dwarfs the top loader! Look at how massive it is.

Maybe future revisions will see it shrink, and maybe due to smaller PCB sizes, the cost will go down as well.

[evil_ash_xero]

Thanks for the vids.

Can I do a vid request? Focus on the TV (full screen) and switch between the different color mods to show us the difference? Do it in spots where the video will not move.. e.g. world map in SMB3, or enemy select screen in mega man?

I'd like to see what all the hype is about the different colors.

If you want to do some serious testing for yourself (not that a video wouldn't be appreciated), you can download the emulators the palettes came from. They're mentioned in the first post.

A good test would be done with games implementing the colour-emphasis bits: http://wiki.nesdev.com/w/index.php/Colo ... asis_games
These games would appear completely grey if the system was using one of the original RGB ppus.

can't wait for the re-up, OP! keep us updated!

[frsj8112]

I wonder if I've broken somethin

After I was tidying things up to make the board fit in the AV Famicom shell again, it just gives me a grey screen when starting games again

The cart slot and carts are clean, what could have happened?

[alamone]

Are you by chance using the original AC adaptor for your Famicom?

When I was doing the PPU based RGB hack I ended up frying a couple of AV famicoms and I think
it is because the original AC adapter only has enough amps for the AV famicom and nothing else.
I never ran into this problem when hacking a toaster NES.

Yes I'm using the original japanese AC adapter. Is there anything that I can check before desoldering the NESRGB and putting the PPU back in the original location?

A solid grey video signal comes out of the NESRGB board before the game initialises the PPU. If you see this it means the CPU is not executing code. After running the Famicom for a few minutes put your finger on the CPU and PPU to check if one is warmer than the other.

Do you have a multimeter handy to check the power rails?

[frsj8112]

Thanks viletim, I'm going to see if one or the other gets warm, can be harder though with the CPU when it's under the NESRGB.

Yes I have a multimeter.
I checked the +5V from your regulater = fine
Checked +5V on the PPU installed in the NESRGB = fine

Damn so u can't use an official nes PSU if using this pcb?? On that note can u use a official UK NES (front loader) PSU on a NTSC US front loading NES??

Regarding the scart cable, I never ordered one as viletim was all sold out, does it use the same din plug as a Megadrive 2, in which case if I wire it up correctly inside the NES I can just use my MD2 scart cable?

[viletim]

Not at all. The original power supply should be fine.

No, different.

That is good news. :D Is it possible to make a reservation list for the guys who were out of luck with the first batch?

If you send me an email I'll let you know when they're ready. I'm not taking reservations/pre-orders.

any chance you can tell us about this 5v->12v "pump" inside the scart cable?
this can be VERY useful to systems like the sms and md that don't have 12v and default to 16:9 on tv sets...

I plan to have it for sale separately. It should be easy to install into all game console SCART cables.

Tim, please let us know if you are doing something fancy in your comparator circuit that makes your c-sync better than what an lm1881 would give from c-vid.

Nothing too fancy. What's wrong with the LM1881?

I think he says if you got something better rather than it being bad on its own

awesome then!!!!
I have bought an av-famicom in the meanwhile and it would be great to use a stock snes rgb cable on the existing port since the pins are there not connected to anything, hopefully the "pump" will be an easy integration as well.

[sammargh]

viletim if you leave the composite video output hooked up as-is and don't run it through the outputs on the NESRGB pcb will it still be regular composite output or will the picture be off-color because of the ppu stuff going on?

right.

Tim, now that I look at the board, are you using an lm1881? Also, I forgot you encode your own c-video from your RGB. So I guess if we are connecting directly to something requiring c-sync it would be best to use your c-sync instead of stripping our own from your c-video, from a theoretical S/N perspective.

Added:
Now I'm thinking about wiring the PPU c-video to my SCART cable for use with all displays, as I plan on only using RGB
That way the sync will go from:
PPU -> stripper in display -> display

instead of:
PPU -> your stripper -> stripper in display-> display (if using your c-sync)
or:
PPU -> your stripper -> your encoder -> stripper in display-> display (if using your c-video)

Pheew

I've just desoldered the CPU and soldered a new CPU from my NTSC NES plus PPU and now I have composite signal back again!

Now I just need to desolder the PPU from the NESRGB to see if it makes any difference with the new PPU.

[leonk]

I can see that the PPU solders to the NESRGB. Does it makes sense to socket it? Will it have clearance in the system (toaster or top loader) if it's installed like this?

Tim says it won't fit that way in the front loader and I don't think it would with the top loader or AV Fami either.

[cr4zymanz0r]

Actually, I wonder if he's referring to if you're keeping the bottom RF shielding and if it would fit with the PPU socketed if the RF shielding is removed (or if removing the RF shield is required to make the rgb board fit at all).

No, you can definitely make it fit, and leave the RF cover on too. Yes even with a socket.

Only know about AV Fami, no idea about toploader but there is no reason it shouldn't be the same situation, unless the RF box is in the way or something.

[ApolloBoy]

No, you can definitely make it fit, and leave the RF cover on too. Yes even with a socket.

What about with the front loader? There's not that much vertical clearance in the front loader and I don't think a socketed NESRGB with a socketed PPU and RF shield would fit.
