The 2009 SourceForge.net Community Choice Awards have started. The Scary Robot is the mascot for the award.
ScummVM is asking for votes for Best Project for Gamers.
I noticed that another great project is asking for votes in the same category. Though not DOS-related, I'm voting for DeSmuME because it is, by far, the best Nintendo DS emulator at the moment. In fact, it's pretty much perfect, while all other DS emulators still have obvious shortcomings when playing commercial games.
I assume that most people around here would vote for DOSBox, though they're not asking for votes on their site. DOSBox was SourceForge's Project of the Month for May 2009! Congratulations!

Also clearly deserving, and of interest to the DOS community, is Bochs, an x86 emulator.
Other candidates worth considering:
FCEUX is also a SourceForge project, but they aren't asking for votes on their website. FCEUX is definitely the best NES emulator (though not by the margin that DeSmeME has over other DS emulators), but FCE Ultra has been around for a long time and most of the significant work on it was done in the past, whereas DS emulation is in its infancy.
ZSNES, my favorite SNES emulator, is also a SourceForge project, which also isn't asking for votes because it hasn't posted any news since 2007.
I was really excited about PearPC, a PowerPC Macintosh emulator, when it first came out, but there has been no activity since 2005. Still a SourceForge project, though.
Other emulators I care about are Project64: the best N64 emulator, which is still active (I've been waiting for v1.7 for 4 years!); VisualBoyAdvance: the best Gameboy Advance and Color/mono Gameboy emulator (no activity since 2004); MEKA: probably the best looking interface of any emulator for any system, an emulator for Sega Master System/Game Gear, Colecovision, and some older Sega consoles (no WIP activity for almost a year); and of course MAME/MESS: the best arcade machine and computer emulators, respectively, and the most ambitious emulation project in history -- none of which are SourceForge projects.
What other projects deserve votes?
