Emulador PSP

¿Alguien conoce algún buen emulador de PSP? Descargué el FF Tactics War of the Lions, pero los emuladores que he encontrado no funcionan adecuadamente.

As far as I know there isn't any good PSP emulators yet. The NDS is the only videogame console in this generation that is (more-or-less) properly emulated.

Where can I find a good ds emulator?

no$gba is still the best. Plays almost all commercial games and it's damn fast but it can only display in 1* mode (this means small) and some graphic errors occur (mostly with transparency) ... but there are programs solving that (No$zoomer). And the emulators save function isn't working yet (the game's own save does). So most things are playable with this.

desmume is an other good one. Plays many roms and doesn't have the save issue but it's not too fast and glitches can happen.

Thanks a lot
