Looking further, I noticed that there's no MMU memory bank declared for
TT-RAM, like there's e.g. for ST-RAM:
https://git.tuxfamily.org/hatari/hatari.git/tree/src/cpu/memory.c#n1143
Does this mean there's no MMU address translation done for TT-RAM?
I think two concepts are mixed up here. The code that you are referring
to here (i.e., STmem_lget_MMU, etc.) handles the potential address
translation by the ST's and STE's MCUs, which only manage ST RAM anyway.
But you are probably interested in address translation by the 68030's
MMU, which is handled inside the CPU emulation.
