remove unused memsetb() routine. replace foo ? 1 : 0 with foo != 0 avoid double calculation of rgb components in readbyte() handle byte aligned color components in writebyte() which lets us avoid the read-modify-write and the shifting. surprisingly, the branches in the loop are way less important than avoiding the memory access. this change makes ganes/snes playable at -3 scaling. |
