Big breakthru in the PSP hacking scene this week. A loader has just been released that lets you play 2.00 games on PSP's with 1.50 firmware. Before, if you wanted to play 2.00 games on your PSP, you had to upgrade your system and give up the great homebrew apps that are available on 1.50. Now this new loader lets you have the best of both worlds.
You'll have to rip your UMD to ISO format and replace some of the files on it (plus have a memory stick big enough to store the ISO on), but it works great when you have it all set up. Read about it here:

Just tested it with GTA and it runs perfectly. Haven't tried any other games, but I hear it'll run a bunch of others like SOCOM and the new Mega Man.
