Jcpsp wont load games

[montcer9012]

Some games i own show a black screen after i hit the run button if the right video options aren't enabled; however, game in did run and if i press X, O or START some sound play; if i still pressing the right keys i can get in game because the only problem is a wrong video config.

Those games have in common that they start showing a pop up like the one Hyakki attach a few post up. If you have SonicStage or the Atrac3+ plugin (If this game use sound on that format) you can try pressing some keys waiting for a sound to play.
