It is yes. Do keep a look out though at the growing list of PSN releases of PSX games. There are quite a few PSX games that dont work correctly through Eboots and there is nothing worse than getting so far in a game only for it to bug out due to incompatibility. So I'd always advise where possible, grab hold of the PSN versions. Especially for anything made by Squaresoft! Also, PSN versions (due to sonys own compression techniques) can be a hell of a lot smaller than ones you make yourself. For instance, Rayman, with CDDA comes out at over 500mb on a homemade eboot. PSN version? 90mb! And nothing is missing.
