I wrote my own GBC emu about a year after you, and an NES emulator, working on and off, from about 2008-2014, doing bits at a time. It's amazingly gratifying when more and more games start working in it. I'm going into Game Boy Advance now. Even just efficiently decoding ARM opcodes is an adventure on its own. Different timings and bus widths in different parts of the memory map....but a large enough map that you don't have to worry about banking at all. Although I suspect that it's fast enough that it might start making sense to look at dynarec/jit techniques.
