Update to release v000r08. byuu says: Changelog: - rewrote sprite rendering, grabs first ten sprites, draws them in revere order of a: X-index, b: OAM appearance order - simplified tile decoding to use less variables - added MBC3 emulation (for now, RTC is always enabled) - STOP can be broken via joypad IF, this may not be correct though (it may trigger even without P10-13 being modified) - cleaned up all MBC emulation to use masks instead of ranges - MBC2 uses 512-byte table now, ignores high 4-bits. Easier this way I guess - tools menu temporarily has a console tracer enable option - some other stuff No real visible improvements :(

Update to v084r06 release. byuu says: Changelog: - fixed sprite tile masking for 8x16 mode (fixes Zelda: DX sprites) - HuC1 flag sets RAM writable, not RAM enable (fixes Pokemon Card) - removed within<> template, didn't turn out to be all that useful I would be almost certain no games would break by allowing reads when it is disabled, no game would rely on that behavior. I prefer to be overly restrictive. Better to not allow valid behavior than to allow invalid behavior. The latter is what gives us a dozen broken SNES translations.
