Basically Mapper 126 (Super Joy), although Nintendulator's and Nestopia Plus' CHR bankswitching is still off.
Is it within the realm of possibility that you mistakenly flipped the 256 KiB banks during dumping? Because it works perfectly as Mapper 126, CHR and all, all 118 games, if I invert CHR A18 in Nintendulator. It may be a PCB variation, but it seems kind of odd, because CHR A19 is normal.
