Yes, I would think that's one of the filing system extended vectors, specifically the ROM bank entry. So yeah, it'd make sense to zero out everything except that bank.Edit: Ah, does &DC2 contain the ROM bank number of the current file system? That might make sense with some of the later code where it is attempting to write to every ROM bank except the for the bank number stored in &93. I think this is where the code is trying to establish which banks contain available RAM.
I think it's probably just trying to "unplug" any paged ROM that isn't the current filing system. Some ROMs like Disc Doctor were known to interfere with certain games, so maybe this is just a way of disabling everything that it can.
