Re: [hatari-devel] Release 1.6.2 in mid May

In complement to my previous mail, I've tried to be as accurate as 
possible with 68030 cycles, except for the cycles that are written as 
"MAX" in the documentation.
Maybe adding the TT to the hatari_falcon exe could improve the TT 
emulation, I really don't know.

I think it may be possible to choose a TT from the falcon exe emulator, no ?
