Differences in documentation[edit]

Both Nestopia's and MAME's sources claim that mapper 171 = KS7058 is something similar to Sunsoft-1, not MMC1. —Lidnariq (talk) 16:03, 13 April 2018 (MDT)

I'm basing my description on FCEUX' source code. The ROM image writes the same bank data both to MMC1-compatible addresses and those odd F000/F080 addresses. Since the FCEUX source code names a chip ("KS203"), I assume that FCEUX is closer to what the board hardware actually does. NewRisingSun (talk) 16:58, 13 April 2018 (MDT)
