Why do I take Nintendo gear apart? To swap MaskROMs
for FLASH chips. Much fun
to create one's own game for a Gameboy. Even more fun if you design a cart
from scratch that actually does something useful (read: logic analyser,
oscilloscope, ...)
I assusme you've seen the Elektor GBDSO project? (Game Boy Digital
Sampling Oscilloscope). Looked interesting, but too proprietary for my
taste (no sources for the firmware are available, for example).
Has somebody done a logic analyser for the Gameboy? Or is this just an
idea of yours?
