Emulator Problem: JPCSP problem

I try to load the UMD but it never appears. I have put the file in UMD images but it never appears in load umd. Also if I try to load file nothing happens. When I run the tests they work perfectly. Whats the problem ? What do i need to do? The game is Naruto Ultimate Hero. The site I got it from says it playable. When I click on a certain file its starts to run but game never starts.

try with another emulator

The most important thing that you should know : psp emulation is new! So not all the emulators work perfectly .

And about the game is it .iso or what?!

And had you tried the new version of pcsp in the site 0.5.5 or the newest version of jpcsp ( it was added yesterday)
