No, no, I said it in the good way. Having guys like you in the threads is a great pleasure. This help to improve emulation.

>> And probably the exact cycle timing, and a better 68030 emulation, no ?

>From what is said (MMU is the main and nearly only gain), I was just thinking about 2 ways for doing it :

1) start with WinUae Code and adapt every single patch from hatari into it. 
2) just add the MMU code in our actual uae core.

The first one would be closer to actual WinUae code but will generate a lot of probable regressions. If it is well done, futur WinUaE patchs should be easier to include (diff patchs for example, without réintegrating everything each time)

The second one let us start with a well tested and known UAE CPU in Hatari and just add the MMU code. As this UAE core is already patched for Atari's purposes, we would continue to diverge from the old branch. But word should be simpler and it would generate less regressions.


Some advise here before I start the main work ?
