Why is clock cycle accuracy not important?

Because cycle accuracy does not matter for Amigas with anything havng a 68020 or higher CPU. Only programs that require a 68000 need cycle accuracy, and we are able to provide that.

What does matter is that when an instruction executes, the end result, including the status register, needs to be correct!

But this software isn't a cpu tester. It it's just an emulator checking itself. In no manner will this program test a real 680x0 cpu.

Better is to rewrite all the tests present in testcases/ dir in full asm. Merely compiling the whole program is nonsense.

Besides, it may well not be working on a real 68k at all because it's designed for the pc and would get endianness issues...

It was created on an Amiga, designed to be a CPU emulation system that was portable to PC, Linux, Mac, etc... I wanted to rip out the tester portion and make it all assembly code (relocatable) that could be just loaded anywhere in memory and ran.

I am going to look at each the tests, the code has the Amiga sample result as a comment. I will just go that route.
