Rolf is working on designing a replacement board that can accommodate a DMG CPU as well as an Atmega168 that can be used for “ArduinoBoy” (a microcontroller program that allows a Gameboy to be receive MIDI) as well as holes in the PCB for the ever so popular “ProSound” mod.
Only some DMG revisions have the chip type CPU; most have an epoxy blob type CPU. However, a SGB CPU can be used instead. Not only are they pin, and otherwise, compatible, but the SGB CPU provides a fast and silent boot process without showing the Ninty logo or playing the start-up sound.
