English Amiga Board - View Single Post - Problem with cycle-exact and custum CPU emulation speed

Nobody said anything about non-68020 until it was too late...

Only 68000 and 68020 have real cycle-exact support (68020 accuracy is much worse than 68000).

Other CPU + cycle exact = chip ram accesses are slowed down by Agnus DMA, nothing else. Freezing is a bug (I guess) but also CE + non-CE CPU is unsupported configuration.
