Update to v089r14 release.
byuu says: Changelog: - NSS emulation improvement (DIP is 8-bits, not 16-bits; can be remapped via XML now like all the other chips) - SA-1 memory map improvements (IRAM and BWRAM can be saved; ROM, IRAM and BWRAM are separate from Cartridge::ROM, RAM; no MCU) - S-DD1 memory map improvements (ROM, RAM inside mapping; no MCU) - SPC7110 memory map improvements (ROM, RAM inside mapping; no MCU; not finished yet [have to handle 8mbit expansion somehow now) I have tried multiple times now to get the SuperFX core to use internal ROM and RAM (separate from Cartridge::ROM, RAM) to no avail. Not sure what the hell is going on there. Trace logs of 430MB are not enticing ... So right now: SuperFX, SPC7110 and BS-X cheat by mapping stuff to Cartridge::ROM, RAM still. They need to not do that.
