Mapper 268: Correct the emulation of submappers 2/3 based on Cluster's report. Add submappers 8/9, used on Retro-Bit re-releases of Star Wars/The Empire Strikes Back.
Add Mapper 354, used on three multicarts (250-in-1, 400-in-1, 1050-in-1).
Add submapper 1 to mapper 452 for the "創新超強卡 150-in-1 技術功能的結晶品質信譽的保證" multicart.
Add submapper 2 to mapper 227 for the "1992 120-in-1 超級金卡" multicart.
Rewrite the emulation of mapper 195 according to nesdev description which was based on real hardware analysis. This rewrite means that the original unmodified version of Captain Tsubasa 2 Chinese now runs, along with the original release of Columbus Chinese, while two of the three protection-removing hacks no longer work.
Rewrite the emulation of mapper 199 according to nesdev description. The previous deprecated understanding was basically a subset of what is now mapper 176.
