OK I think I am well experienced in this process, I have converted lots of PSX isos to eboots that worked flawlessly on my PSP. Yet, certain games just refuse to play soundtrack during gameplay. Those are, for example Destruction Derby, Motorhead, Vanishing Point - all driving games. Does anyone have an idea what might be wrong? I've been using PSX2PSP 1.4.2. Why some games work perfectly, whereas in others the soundtrack (the music that plays during a race) is missing? Oh, and I DID try to change the settings like disabling the fast CD reading and changing the POPS version at the start of the game... Thanks for any advice.
