putty, from the same forum as the people who brought us 6.3Xpro managed to repack and sign an iso of angry birds so it could be launched on any PSP with firmware 6.20 or higher, no need for an iso loader, or cfw. he claims it can be done with any game under 720MB(limit might change if he can find a bigger demo game as source) his method is to replace the iso in a demo game's eboot.pbp with the iso of a full game, and perhaps some magic or soul-selling. i have tested his "signed' copy of angry birds and it works as good as if i had bought it myself from PSN. because of rules on this forum i can't link directly to the source topic, since it contains a download link to angry birds. this is another big blow to sony, running pirated software straight from the XMB on official firmware.
