Now that an exploit has been found via a glitch in the GTA PSP game, I can see people buying the game just to have a way of running homebrew on 2.01/2.50 PSPs.
My theory is that Sony and Rockstar will release a 1.1 version of the game to fix up this hole perhaps.
Could they do this with no way of us knowing which GTAs will be exploitable or not?
This is basically my worry about this exploit. Of course, a newer GTA wouldn't stop others with the older version...
Maybe they won't do this, but who knows?
