Fceux SVN r1923 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:
r1920
frame counter turns red on MOVIEMODE_FINISHED
r1921
fix up opening roms from archives
r1922
Added Single Instantiation mode, which makes starting a second copy of FCEUX with a path to a game make it load the file into the first, then exit. To enable, set SingleInstanceOnly 1 in the config file. If someone else wants to edit things to make this easy on the user, go for it. If started with nothing in the command line, it will simply start a second copy.

Win32 - Hooked up SingleInstanceMode to a checkbox in GUI config.
