Hi,

A few tests done with the new core :

- rainbow 2 (use the MMU) : OK
- X_tasie demo (runs with MMU) : KO (probably because of CPU timings, as it's locked between DSP and CPU exchanges) - _ demo : it seems to have regressed (both 68030 and non 68030 cpu). Before, it was running at least the 3 first screens before freezing, but now it freezes at start.

- a few more demo tested, that are working, (they probably don't use the MMU). But with the 2 cycles instructions timings, they look strange, or music is full of glitches, ...

I'll do some more tests.

The best now for hatari would be to have 68030 + MMU + cycle exact (nevermind if the MMU instructions are not cycle exact, there's never involved in time critic loops).

That's the Falcon standard CPU.

Thanks for the new CPU Tony and Nicolas.


hi

thanks for the tests ; for those that don't work, did they work with Hatari 2.0 and the same settings ? It's important to know if regression is due to latest MMU changes or if it was already wrong before.
