Re: [hatari-devel] 68030 MMU emulation: TEMPLMON, ROMSPEED

Hello Uwe,

after some more research it seems i don't have this problem with the unaligned access function on my system. What system and what compiler are you using?

It is very strange, that the debugging output is scrambled. Is the text in your mail exactly what was printed?

Regards,

Andreas
