Here's how to use it:
* Replace your existing popstation.exe with the one in the archive (either stand-alone or along with a GUI)
* Rip your CD or convert your existing image to CloneCD format. You should have a .ccd file with the same name as your image file (for example, game.img and game.ccd or game.bin and game.ccd).
* Make sure the image and .ccd files are in the same directory and run popstation.exe, or your GUI of choice as normal and now CD audio will work.
Tinnus has included the source code with this application and has confirmed that Tomb Raider, ripped to .img and .ccd, converted to EBOOT with PSX2PSP 0.7 at compression level 9 works with this, and so should any other game using CCD audio. We at QJ would like to say a big thankyou to Tinnus for this as it will make it much better playing those old PSX games for a lot of gamers.
