I see there are a few colors missing, but isn't it a common thing that AV modded systems appear darker during gameplay? Mine does that, and from the looks of it, so does popi's.

On HDTV's (Mine's a Samsung) ,It does some ghost stripes when in component. I tried using  the (s)nes control deck RF Cable and it doesn't work,the damaged pin one that has the Nes Control Deck on it works perfectly so I don't know why the NES control deck can work on channel 95 and the other new one won't work.

133mhz is the master?


Can he tell me how to get my gameboy color  to play on my TV? I'm trying to make it unPortable. or something.

Now that you mention it, the Game Boy is a pretty weird beast. It's an LCD based system, but it uses CRT-based timings and sutff, like HBlank & VBlank periods, it even provides sync pulses! Maybe Nintendo did this because developers were accustomed to programming CRT-using systems and expect those kinds of things, even if they are completely irrelevant on an LCD.

So the LCD really works as a CRT, the only different thing is that the video is carried by two separate signals, each one containing two of the four possible shades of grey. The combination of those gives you the full spectrum, like three separate video signals give you every possible color on a VGA monitor.

Display Resolution: 160x144 pixels
Horizontal Scan Rate: 9.615 kHz
Vertical Scan Rate: 58 Hz

The H-scan rate is really weird and the lowest TV sets ever made that can support such a thing are old British 405 line sets (which work at 10.something kHz horizontal). Normal TVs around the world run at 15.7 kHz and PC monitors start at 31.5 kHz for 640x480. So, if you're planning to connect the thing directly to a TV or monitor, you're SOL.

The only possible way would be building a full digital frame store which reads a frame of this weird-ass video, and then fitting a D/A converter which reads said frame and converts it into a standard NTSC/VGA frame, rinse, repeat 60 times a second and you get a normal video stream. TV-out circuits in modern PC video cards do this sort of thing.

If you're the Omnipotent God of Digital Electronics™ and possess shitloads of cash for FPGAs and stuff, then this should be a piece of cake :P

What?


I guess i bought another gameboy for *almost* nothing. my other one needs a speaker.

I guess that if I put a yobo inside of an n64, I could turn the gameboy into a controller.


8-BIT MULTYGAEM, I will call it.

Yes, but it will be a PITA to connect and disconnect every time you want to play your FC. OTOH it will give the best quality you can get out of RF.

Yes, get a gameboy snes cartridge (forget what they call it...)...  :)

or pony up the cash for a wideboy:

or get yourself an oldschool gba at a yardsale and get a gba 2 tv adapter:

If you really want the gb controls, turn your extra gb into a snes controller...

You're giving the practical answer. I'm giving the excessively technical and complicated answer :P.

Doesn't the Game Boy Player for GameCube take old carts as well? You can get a Japanese boxed set of a Spice Orange console with the matching coloured GBA player and it looks well nice ;)
