byuu says: Changelog: - Z80: emulated 83 new instructions - Z80: timing improvements DAA is a skeleton implementation to complete the normal opcode set. Also worth noting that I don't know exactly what the hell RETI is doing, so for now it acts like RET. RETN probably needs some special handling besides just setting IFF1=IFF2 as well. I'm now missing 24 ED-prefix instructions, plus DAA, for a total of 25 opcodes remaining. And then, of course, several weeks worth of debugging all of the inevitable bugs in the core. |
