[hatari-devel] Some wrong assumptions about EmuTOS capabilities

[Thorsten Otto <admin@xxxxxxxxxxx>]

When checking for valid CPU/ROM combinations, Hatari currently assumes that EmuTOS can handle everything, but that is only true for the 512k version. The 192k versions don't have support for anything but 68000, and the 256k versions don't have TT support.

 

For example i just accidently tried to use the 256k version in TT mode. That causes XCONTROL to crash, because EmuTOS detects a MSTE as machine-type (because of the missing TT-Shifter support), then xcontrol (or more precisely general.cpx) tries to access the cache control register at $ff8e21, and crashes because Hatari configured I/O for TT, were that register does not exist.
