Spongebob's Truth or Square not Loading

[iinickb]

Hi. Recently, I decided to revisit ppsspp and a game called "spongebobs truth or square". I was going to play it on my real psp, then i realized that my real one was broken. so, i got the newest version of ppsspp and loaded up my game iso. (note: i modified some music on the iso because some of the psp games tracks are like 20 second loops and it gets on my nerves.) it used to work back when i used ppsspp v1.0, now, it just says it cant read the disk whenever i load into a level. got an idea as to why this is? (just as some backup info, the music tracks i had in the game were approx. 30 mins long each because i dont know how to make them loop.)(they are shown as .wavs but theyre actually .vag) help is appricaited!
