It's not a bid deal but... I've become interested in low level programming some time ago. During past 5 months I've been working (not with the diligence I wanted) on a GameBoy emulator written in C++. It started with me trying to emulate the gbz80 chipset, then the "why not?" question did hit my mind.

Actually I have finished the CPU fetch-decode-execute cycle, so I'm implementing the CPU instructions and looking forward to implement a basic version of the MBC and get cycle accurate.
