Update to v099r15 release. byuu says: Changelog: - nall::lstring -> nall::string_vector - added IntegerBitField<type, lo, hi> -- hopefully it works correctly... - Multitap 1-4 -> Super Multitap 2-5 - fixed SFC PPU CGRAM read regression - huge amounts of SFC PPU IO register cleanups -- .bits really is lovely - re-added the read/write(VRAM,OAM,CGRAM) helpers for the SFC PPU - but they're now optimized to the realities of the PPU (16-bit data sizes / no address parameter / where appropriate) - basically used to get the active-display overrides in a unified place; but also reduces duplicate code in (read,write)IO
