what in god's name is WROM?

Are you new to 6502, NES, or even programming in general? Post any of your questions here. Remember - the only dumb question is the question that remains unasked.

WROM = Writable ROM?

Threaded bank-switching = mapper keeps track of multiple threads of execution and switches banks automatically during a context switch? (not sure how it would make much of a difference in the work required to switch contexts; see Multithreading Demo).

EEPROM? Flash?

There were some Atari 2600 mappers that would watch reads and writes in the stack and bankswitch depending on how deep the last access was. So programmers would place subroutines below a certain depth in bank 0 and the rest in bank 1.
