ExultPSP is a port of Exult, a framework which allows you to play Ultima7 (The Black Gate and Serpent’s Isle and their addons) on the PSP. Ultima 7 inspired or influenced most modern RPGs, from Baldur’s Gate to Oblivion.

There is a big update to ExultPSP, which now supports Slim PSPs with CFW, Serpent Isle is playable, there is TV-Out support, and more.
