Ugh, IDA, why are you ignoring the data bank register in this disassembly?? Maybe half the memory references in my disassembly are completely bogus because IDA "helpfully" mapped them into memory, but in the completely wrong place...

I gave up and split the auto-generated WRAM segment from $7E0000-$7FFFFF into two segments from $7E0000-$7EFFFF and $7F0000-$7FFFFF. This way I can automatically fix references into the second bank instead of rewriting them all manually, and IDA will even keep track of the RAM address's name if/when I name them.

I also figured out that I can manually rewrite code instructions, so I can turn all the one-byte BRK instructions into actual BRK instructions!...that aren't actually marked as code. >.>;; Oh well, at least it will be less ugly this way...
