maybe , i think it would only mess up the game or data.
so prolly only if you saved the data onto ur psp

Scan it with Norton it might find a trogin.brick virus in it....

No way possible. I mean if you got 2.00 the only exploit known for it has nothing to do with a saved game. If you got 2.00+ then your safe there too because in order for it to break your PSP would mean it had the ability to access your flash(psp system files) and its just not possible. The most you could "brick" with Edisons Cheat Device is one of your saved games in GTA:LC if you saved it with some cheats running. If you could brick your psp using the method in his hack works in then we'd already have a working exploit and a real 2.5 downgrader would of already been released

i agree with drmadcow, it wouldn't affect the flash at all, unless you tried to activate a downgrader or something, then it might screw something up. but if ur talkin about like just an edited file for cheating or something, then definetely no.

Yes, it's possible. The GTA cheat runs real code on 2.00, 2.01, 2.50. The chances of it happening by accident are incredibly slim (only a little higher than the chances of a working exploit being found by trying to hack TIFF code into random files... ). But it would be possible for someone to write a malicious savegame hack that did this.

No. Norton only scans for files called overflow.tif in order to spot the brick trojan. PSPSafe wouldn't spot it either, because the code is encrypted.
