OK, I've had a PSP1000 for years so I finally decided to put some CFW on my PSP. Where I've been using flash cards on my DS I assumed you needed the latest firmware for game compatibility and so on so I put 5.50GEN-D3 on my PSP. Now I've had no problems with the PSP games, everyone I've tried works, even the newest but my problem is what do I do with PS1 games, I've tried PSX2PSP with PS1 ISO's (not retail, downloaded) all I get is a black screen and I just can't get my head around Popsloader. Hope no thinks I'm being lazy starting a new topic but I've gone through this forum and Google and I just can't get my head around it, I'm totally stuck. So any help or advice would be much appreciated. Edit- Sorry I should have put 'Needed' in the title.
