byuu says: Changelog: - GBA: lots of emulation improvements - PPU PRAM is 16-bits wide - DMA masks &~1/Half, &~3/Word - VRAM OBJ 8-bit writes are ignored - OAM 8-bit writes are ignored - BGnCNT unused bits are writable* - BG(0,1)CNT can't set the d13 - BLDALPHA is readable (fixes Donkey Kong Country, etc) - SNES: lots of code cleanups - sfc/chip => sfc/coprocessor - UI: save most recent controller selection GBA test scores: 1552/1552, 37/38, 1020/1260 (* forgot to add the value to the read function, so endrift's I/O tests for them will fail. Fixed locally.) Note: SNES is the only system with multiple controller/expansion port options, and as such is the only one with a "None" option. Because it's shared by the controller and expansion port, it ends up sorted first in the list. This means that on your first run, you'll need to go to Super Famicom->Controller Port 1 and select "Gamepad", otherwise input won't work. Also note that changing the expansion port device requires loading a new cart. Unlike controllers, you aren't meant to hotplug expansion port devices.
