It's a Japan-Only PSP series about a bunch of Super High School Level weirdos getting trapped in a cross between Battle Royale and Ace Attorney by evil robot animals. The English fanbase is built primarily around a pair of Let's Plays by Something Awful user Orenron. There is also an actual patch in the works for the first game but it came in at the tail end of Orenron's LP, is terrible, and will be forgotten since apparently Oren's working with some other people to get a patch done based on the LP translation anyway.
The thread for Dangan Ronpa 1, completed save for a few side scenes with the various cast members which are basically Fire Emblem supports:

e1: If you want to play the first game, here is a garbage translation of it while waiting for the proper patch from Oren and company.

e2: If you've played DR2/read DR0 in Japanese, please have the decency to either not post at all, or label any spoilers of untranslated material as such.
