Fceux SVN r1422 is released.FCEUX is a cross platform, NTSC and PAL Famicom/NES emulator that is an evolution of the original FCE Ultra emulator. Over time FCE Ultra had separated into many separate branches.The concept behind FCEUX is to merge elements from FCE Ultra, FCEU rerecording, FCEUXD, FCEUXDSP, and FCEU-mm into a single branch of FCEU. As the X implies, it is an all-encompassing FCEU emulator that gives the best of all worlds for the general player, the ROM-hacking community, and the Tool-Assisted Speedrun Community.

Fceux SVN changelog:
r1421
Reworked many things relating to joypad_set. New logic, removed a few functions, all that stuff. Hopefully a few bug fixes with no new bugs on the way. Haven't put in the invert that I like, but hopefully that isn't hard to put in.
r1422
Added in an invert possibility for joypad_set. Using a string instead of true/false/nil will let lua invert the player's input.
