There is also Exult, which can run Ultima 7: The Black Gate and Part 2: Serpent Isle. Note that the current Exult port is not fully compatible with the fat PSP, though it will still run. If you play it on a fat psp, it will hang often due to a lack of memory. With a Slim, it only locks up every half an hour to an hour because of the extra RAM. Oh, it also has native TV out support, so no need for FuSA. Oh, and Exult is only a replacement engine (interpreter), you still need to obtain the data files for the game. The same goes for SCUMMVM, which can play many Lucasarts point and click adventure games (maniac mansion, day of the tentacle, monkey island series, etc) but you still need the original game data.
