INES Mapper 033

iNES Mapper 033 represents Taito's TC0190. It also represents a subset of Taito's TC0350, but the only game we currently know to have used that IC didn't use its interrupt abilities (which are identical to those described on iNES Mapper 048).
Here are Disch's original notes: ======================== = Mapper 033 = ======================== Example Games: -------------------------- Akira Bakushou!! Jinsei Gekijou Don Doko Don Insector X Note: -------------------------- Most dumps of mapper 048 games floating around are erroneously labelled as mapper 033. Mapper 033 does not have IRQs, mapper 048 does, and mirroring on each is handled a bit differently. Apart from that, the two are very similar.
