The PS3 version of NBA Jam: On Fire Edition is now fully playable on the RPCS3 emulator. Earlier this year, the game became playable, but the jersey textures were missing so all the jerseys were solid black. Sometime in the last month this was fixed, and the game runs beautifully now. Here's the game's thread on RPCS3's forum:

I haven't figured out how to get the last roster update that EA released for this game (the one that added the 2011 rookies). I believe the update is downloaded from within the game, directly from EA's servers. There is currently no network mode or PSN support in RPCS3. I'm thinking the game files will have to be copied directly from a PS3 that has the updated game files.
