Updated code was pushed, Hatari now matches the result of your
mscatest.tos test program, both for DTA structure and for bus error access.

 

Thank you. Imho, DoWrite should also be considered for the TOS ROM address space:

https://framagit.org/hatari/hatari/-/blob/main/src/m68000.c?ref_type=2ac4b923ad6747b8ca1180df3b00cc03adf3e882#L1269

 

Otherwise, writes to TOS ROM will cause a cache update, regardless of the bus error that happens, won't they?

Hi

yes, stupid me ; DoWrite was in fact intented at first to exclude ROM region, and I forgot to add the test for it :(

Will push a fix for this.
