issue emulation

Hey everyone, There is an issue with my ps2 games I bought at the ps store for my cfw ps3. Whenever I go activate it using my psn account, some ps2 games work which are usually the ones I have not opened yet. But once they have saved data, they almost never run and shut down once I load them...

Hi. I Have a CECH-2101A model and it's running with Evilnat 4.89 CFW. I never tried to run ps2 games before so a few days ago i decided to give it a try. I placed the .ISO and .CUE files on PS2ISO folder and then mounted using webman mod. But when i open the game my tv goes to a "No signal"...
