byuu says: I now have enough of three instructions implemented to get through the first four instructions in Sonic the Hedgehog. But they're far from complete. The very first instruction uses EA addressing, which is similar to x86's ModRM in terms of how disgustingly complex it is. And it also accesses Z80 control registers, which obviously isn't going to do anything yet. The slow speed was me being stupid again. It's not 7.6MHz per frame, it's 7.67MHz per second. So yeah, speed is so far acceptable again. But we'll see how things go as I keep emulating more. The 68K decode is not pretty at all. |
