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.	2016-07-12 20:19:31 +10:00

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

isn't going to do anything yet.

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
