After sticking to Nintendo for a while, I decided to start a Sega Master System emulator. The Game Boy CPU is similar to the Z80 processor found in the SMS, so I was luckily able to reuse some source code. After implementing part of the Video Display Processor, I finally got one test ROM up and running, as seen above. The mapper work should be much easier than the NES and I should hopefully have a few games running soon!
