Incidentally, do you think those issues could be caused by mirroring where no mirroring is present, or having no mirroring where mirroring is present?

Basically, what I want to know is: if the SuperFX reads from a SuperFX memory address of 0x712345, does it actually read from index 0x2345 in the FX RAM buffer? If the S-CPU reads from 0x356789, is this the same as a read from 0x306789, which itself is a read from index 0x789 in the FX RAM buffer (due to mirroring)?

Thanks in advance.
