It's not a banking problem.
The behavior looks identical to the issue with Savage Quest, which was definitely an incomplete BIOS.
However, in this case, it's that the BIOS is moving a block of memory out of the way for a while, and then not putting it back before attempting to call it. I suppose that one of the ports is not returning the expected value.

The other two are 0f 78 and 0f 79.
