byuu says: Lots of improvements. We're now able to start executing some V30MZ instructions. 32 of 256 opcodes implemented so far. I hope this goes without saying, but there's absolutely no point in loading WS/WSC games right now. You won't see anything until I have the full CPU and partial PPU implemented. ROM bank 2 works properly now, the I/O map is 16-bit (address) x 16-bit (data) as it should be*, and I have a basic disassembler in place (adding to it as I emulate new opcodes.) (* I don't know what happens if you access an 8-bit port in 16-bit mode or vice versa, so for now I'm just treating the handlers as always being 16-bit, and discarding the upper 8-bits when not needed.)
