Problem with Spyro Year of the Dragon

Can someone please explain what is going on? I recently put YOTD on my psp and it was working fine up until the second world. For some odd reason, butterflies are killing Sparx. He will eat one and disappear. also, i seem to be traveling in a cross between a rocket and a baloon. When i want to go somewhere, i am forced to fight the first boss, then i am sent to some place called Super Bonus Round, where all the doors need 18000 gems to open. so, was there a problem with my ISO when i converted it to EBOOT, or does that just happen?

this sounds like a major malfunction somewhere. Can you try the game on a PSX emulator?

i searched around, and i found out that it has something to do with the fact that sony put some kind of copy/crack protection on the game. it causes these problems apparently to discourage people from illegally copying it.ill try your method. thanks for the help!
