Well you can try to search for bytes/instructions inside a rom file that you see in asm files. If the data is at the beginning/end of the bank, it will be much easier, since banks usually start with 0x00010, 0x04010, 0x08010 and so on (+4000).
Also some assemblers can produce a listing file if you configure them properly.

The dude that made the disassembly left quite a few notes regarding locations. For example the "IsEquipLegal" function from bank 0E which was mentioned earlier, line 9039 tells you where it begins (cpu and rom file addresses).
