Update to release v000r05. byuu says: Fixed all of the previously mentioned problems by myself and Jonas Quinn. Fixed up JOYP and hooked up JOYP interrupts, they work on JOYP writes as well if your selection makes the low four bits change to != 0xF. Added basic sprite emulation, very very very lousy but it works for Tetris. Fixed DAA, fuck that opcode. Fixes blargg's CPU tests 1 and 11 (for some odd reason.) Only test 2 is failing, on the "EI" test. Maybe it relies on STAT interrupts? Did some other stuff. Tetris is now 100% fully playable. But that renderer is an abomination. Soooooo simplistic and missing so many edge cases. But holy shit, a fully playable commercial game in three days. I would have killed to have made that progress when I started on bsnes.

void mmio_joyp_poll();
Update to release v000r02. byuu says: 314 of 512 opcodes implemented, can execute the first 67,450 instructions of Tetris. I also added an MMIO bus, ala bsnes, so that I can map and access individual registers with a single indirection.
