GBA ROM dump from 32 MB ROM with EEPROM is an overdump #221

Closed SNBeast closed 8 months ago

SNBeast commented 1 year ago

The last 256 bytes mapped to ROM on a cartridge that uses EEPROM is the EEPROM registers. For 32 MB carts, this causes those registers to be added to the ROM dump, which is annoying for hash reproduction. The favored solution from the discussion today in No-Intro is to keep the dump at the same size, but fill the 256 bytes with the prior padding byte (to try to match the lotcheck submission).
