The "wsnd" sound enabled version was made really quickly. I have since been working on it and fixed a bunch of bugs that made it crash some games.
Sorry about the bug in the file menu system. I'll fix it asap.
Urielka: With PocketISO 2.0, did you rip anything out (by checkmarking boxes)? For testing it's best to use a .bin or a compressed ISO with nothing ripped out. Since you said .Z, you most likely chose FF8 Search Method and didn't have to checkmark/rip anything out. That's a good thing if that's so.
Both .Z and .Z.table *must* be included together in order for the game to run.
Also, make sure you have scph1001.bin (all lowercase) in the same directory as ZPSX.
HLE currently does not work, as it sucks.
As for performance, I'm able to play games like One Piece Mansion, Buster Bros Collection, Final Fantasy Tactics, and others just fine. I'm almost able to play Street Fighter 3 Alpha and Wipeout XL at full speed, it's just shy of playable.
I unfortunately don't have Dino Crisis 2 or Tekken 3 to test with, but I will try picking them up.
I'll get a working version of sound-enabled ZPSX (with an option to turn off music and/or sound effects) out asap.
