I know several people have said that a 68000 is too slow to run WHDLoad, and I agree with that. I was curious though....is it possible to run it with a 68010? I have used this CPU in the past and saw a slight speed increase on some games but I have never tried it with WHDLoad. Has anybody ever tried it before. If you have, please give me your results. Thanks.
A 68010 is exactly the same as a 68000 except:
It was easy to get them a little faster, like 12 or 16 Mhz
If you plug in a 68010 that is running at 7.15909Mhz as the 68000 then all that changes is:
1. Mul#? instructions go significantly faster. But no self-respecting asm coder uses MUL in a time critical loop
Nevertheless I have seen cracktros run at much higher framerate on a 7Mhz 68010 than on 7Mhz 68000. Obviously they used Muls to calc their 3D rotating gfx. Shame on them
2. 68010 has
Loop Mode Very tiny loops can run from internal cache. Does it really matter to you? Meh
3. On 68010 the Move SR,
instruction is privileged. That means its ILLEGAL. So any game that uses it will work on 68000 and blow up on 68010. Maybe WHDLoad has a fancy patch for this? Donno.
Bottom line: A 68010 introduces software incompatibilities for only a tiny improvement in speed. I say it isn't worth it. But you can do what you want If I was going to suffer incompatibilities to old badly coded gamez then I would just go ahead and use a 68030 or higher.
I always kept at least 1 Amiga with a plain 68000 for 100% compatibility reasons.
