This is a game that originally came out for PSX (Play Station 1) and was modified to be played on a PSP without an emulator, so we have extended menus, different from the original PSP game, even allowing resize screen, load the next disc in the games that came in more than one disc PSX or change the button configuration. So these games come in EBOOT.PBP format and not in ISO work perfectly on a PSP, the only difference is that its location within the memory card is different from the games that come in ISO or CSO EBOOT.PBP van (without changing the name) in a folder with any name (preferably the name of the game obviously) and that folder goes inside PSP \ GAME \ Something like H: \ PSP \ GAME \ NombreDelJuego \ EBOOT.PBP
