The GameCube's internal framebuffer is 4:2:2 YCbCr, so it's either GCVideo converting to RGB or your TV doing it to display the signal.

Good usage scenarios are HDMI on any flat panel that would accept it, 480p component on older flat panels without HDMI, 480p RGBHV for CRT monitors, and 240p RGBS for GBI on 15kHz CRTs.

Ahh thanks for that - so not better quality then. Then the question is - for the Wii, how much of an upgrade the new component/RGB will be from it's existing component signal.

Either way it's amazing to have all those options in one mod for both consoles.

Yes forgot to tell leonk : RGB is nice for plugging the GBA player on 15kHz CRTs that have RGB, but no component.

But it is a moot discussion since the board will have both RGB and YPbPr :D

I actually have a gameboy player but I never actually tried it out!! :(

So the player is always 240p?

The factory disc is 480i but GB Interface let's you set what you want.

Do GB/GBC/GBA games not have a colorspace? If they do, what is it?

Their colorspace is defined by their screens. Standard GBI performs adaptation from GBA to sRGB by default.

oh. so the player can be forced into 480p like some of the GC games?

Yes, 480p works fine and is what I actually aim for.

The NTSC disc will prompt for 480p, but it isn't so great. Nintendo's filtering is still there.

I meant in the context of consoles where the only choices are 480i and 480p, such as the original xbox. If there's 240p available (even for just a few games), I'd like a 240p RGB SCART option as well.

It will output both Component and RGB.

You will be able to choose which output via the OSD or a master input pin. I plan on building a component cable that will plug into the multiout that will trigger this pin and force component mode.
Awesome, so all options are covered! Yes, RGB would most commonly be used for the GBi, or people who use Swiss to force 480i games to 240p (I actually prefer to do that on monitors that don't support 480p).

RGBHV (VGA) will be for people who use PC CRT's for 480p. Many Smash Bros tournaments will benefit from this, as they'll get to use cheap VGA monitors that are lag-free.

Component is a great option to have as well. I'm looking forward to testing this!

I don't believe most commonly used RGB display devices support 480p RGB input (PVM or XRGB). So a gamer will need to either play in 480i or 240p. Right?

The HDMI port of course will be 480p and be optimal video quality output.
SDTVs don't support 480p. Even those with YPbPr component input.
RGBs 480p is rare, few devices input or output it. Usually VGA is used for analog 480p RGB.

Oh okay. Thank you

So which output would yield the best results for GBI: YPbPr, RGB or HDMI?

Yep 480p. But also 240p! which is great for GB, GBC and GBA games IMO. Everyone have their preferences, but to me the Gameboy games look better with scanlines

I couldn't care less about the blanking lines in 240p mode, I'm just happy that it's not shaking in interlaced mode.

Use whichever is most suitable for what you're looking to do, but analog formats can be driven with twice the resolution for scaling transparency and equivalent of 4:4:4. I haven't done the latter yet.

Re: Cloning the Gamecube component cable

I'm really glad to see all the recent love towards the Nintendo Gamecube. Based on my personal experience with installing the GCVideo mod into consoles for customers, here's my dream wish list for a better solution than the standard Pluto IIx one:

- much like the current solution, I would like to see a no-cut solution. The 3D printed PCB holder with digital port to hdmi plate looks very clean and professional. Case modification tends to be the most time consuming part of any HDMI/RGB mod for me these days. This will also allow a customer to swap the outer shell in the future if they ever wish to.

- if RGB out is an option, allow output into the nintendo multiAV port. Make the rgb and sync levels equivalent to what a standard snes puts out (so users can reuse the same scart rgb cables)

- the ribbon cable is not as big a deal for me as I would have thought. Standard install is 18 wires. Not that more than a fully populated NESRGB. If ribbon cable is a bottleneck for production(badass consoles!) then skip it.

Apart from that, I think we have a pretty mature and solid solution!

is there any reason to grab the gc video 2.0 plug n play hdmi if you already have the official cables hooked up to a framemeister?

There is no flex cable. Let me outline how this works.


This QSB sits directly on the digital out pins:

Then the new PCB attaches directly to the QSB.

Image

So the entire FGPA sits below the motherboard. There is a stock FFC cable which transports the TDMS signals to the HDMI (toslink/GND/+3.3 is also sent over to bring the spdif lines close to the install point, if you want toslink of course :wink: ) connector to this board. This connector board sits in the back plastic spot. as seen below:

Image
Image

There will be a final qsb that mounts to the multiout to bring in the RGB Lines etc.

That is the current hardware plan.

Since GBI isn't capable of displaying SGB borders or colors, would it be possible to edit GB[C] ROMs to have those features enabled when playing on GBA hardware?

Much like how Shantae and the Oracle Zelda GBC games work on a GBA.

If I didn't already have a GC video 2.0 plug n play I would definitely be interested in citrus3000psi's internal modification. Never the less, I am still interested in a SPDIF/Toslink mod (since my processor didn't like the enhanced DVI audio). Does any know someone that does this mod and the cost?

You could use Goomba Color, but mGBA recently gained partial SGB support.

Check out this thread I made a while about about just adding toslink.

In their native state, no. GBA doesn't contain SNES hardware.
Some of it can be simulated like Extrems pointed out.

Very nice Citrus! I noticed that was posted about a year ago.
How did it go? Were you able to get it working correctly?
