www.pspupdates.com is the site you should go to. It has all the stuff for hacking your PSP, and is the place for all your PSP homebrew needs. I got a N64 emulator there, and now i can plasy games like Super Smash Brothers 64 on my PSP. Yay!
I have gotten on top and I can live. The map is still in progress though. I'm not done making the finishing touches. Look here and you can see how I did it.
Here's a cool version of a glitched Avalanche I made (78 dl's so far): http://www.bungie.net/forums/posts.aspx ... d=30987012 And here's my Blackout (out of map stuff included)(28 dl's so far): http://www.bungie.net/forums/posts.aspx ... d=32478010 Enjoy!
