* M061: Add CHR-ROM variant. * M227: Make DIP switch change only apply to submapper 1 * M242: Only assume DIP/solder pad read when A0-A7 are zero, corrects ET-187 and Xing-2462. Initialize M227's and M242's DIP switch setting on Hard Reset. * M052: Support CHR-RAM-less variant of submapper 14. * M364: Correct the outer bank register's address mask, for LT-953 multicart. * M047: Supprt larger-sized multicarts using a compatible PCB. Reset to menu. * M360: Add submapper 1. * M221: Rewrite, add submapper 1 variant. * M288: Remove bank masks to allow for already-existing larger cartridges. * M411: Add submappers. * M417: Add submapper 1. * M115: Add multicart functionalities. * M201: Simplify and correct the power-on value. CF-043, mentioned in the source code comment, needs no submapper; just a correct header with Horizontal mirroring. * M200: Correct the power-on value. * M432: Add submappers to distinguish three variants. * Add mapper 412. --------- Co-authored-by: NewRisingSun <8vytz1+dhp372pv94ebg@sharklasers.com>
