byuu says: Changelog: - sfc/ppu/sprite updated to use new .bit(s) functions; masked sizes better; added valid flags instead of using magic numbers - ws/ppu updates to use new .bit(s) functions - ws/ppu: added line compare interrupt support - added ws/eeprom; emulation of WS/WSC internal EEPROM and cartridge EEPROM (1kbit - 16kbit supported) - added basic read/write handlers for remaining WS/WSC PPU registers WS EEPROM emulation is basically a direct copy of trap15's code. Still some unknown areas in there, but hopefully it's enough to get further into games that depend on EEPROM support. Note that you'll have to manually add the eeprom line to the manifest for now, as icarus doesn't know how to detect EEPROM/sizes yet. I figured the changes to the SNES PPU sprites would slow it down a tad, but it actually sped it up. Most of the impact from the integer classes are gone now.
