INES Mapper 146
iNES Mapper 146 is assigned to Galactic Crusader by Sachen according to NesCartDB.
Nestopia implements it as a 100% duplicate of NINA-06. Санчез's notes seem to agree.
It appears to have allocated by the FCEUX developers to work around legacy compatibility code in their implementation of Mapper 79, which simultaneously implements both NINA-06 as well as a no-PRG-banking subset of iNES Mapper 148 (i.e. "CNROM"). Why did they allocate this mapper rather than fixing mapper 79? Are there any files still floating around that are tagged as mapper 79 but are actually CNROM? No other modern emulator's implementation of Mapper 79 has implemented this conflation, so it seems likely that this assignment is redundant.
