so, averybody remember the gameboy colour? well anyone ever played a gbc emulator on the computer with its speed up-space bar function. yeah, i wanna make the actual gameboy do that, anyone know how to do that? i love retro gaming, but my days was it slow.

The only ways that I can think of:

1. Increase the clock speed. Probably by replacing it's crystal with a higher frequency one. You're probably not going to get it double speed though and there's probably more to it.

2. Hack a game. This is more likely to prove successful. I'm sure you can get hacked ROMs that you can load games onto these days google around.

Probable not worth all the effort but if you're into hacking then it's a project I suppose

ahhh, the crystal may work, good call
