You don't need an emulator to play PSX games, it is built in. You need to stick the PSX game EBOOTs in a folder named after the game or w/e you want to name it, then place it in the GAME folder.

EX:

//PSP//GAME//

"PSX".EBOOT

Can I convert ISO into EBOOTs, or do i need the phyical game to make an eboot

Yes, look up icetea or PSX2PSP.

I used popstation GUI2 to convert digimon world img file to an eboot and it didn't work...

You have popsloader enabled?

yea but when i try to start a game i get error FFFFFFFF, I think it was the eboot file so i am going to get aother one to see if it works
