Looking for vulnerabilities in the PSP Firmware  I’ve described
in a previous article how to look for exploits in games on the
PSP. But as you may or may not know, the new PSPGo’s business
model made game exploits useless for the average user.  Let me
explain: if an exploit is found (and revealed) in a Game on the
PSP, Sony will simply remove the game temporarily from the PSN
Store, and it will be available again only if the game’s
developers fix the issue. So the only people who will be able to
benefit the exploit will be those who downloaded the game from
the PSN Store before the exploit was made public. (unless you
didn’t know, the PSPGo has no UMD drive, and therefore all games
for this machine must be bought on the PSN)  Yep, that’s not
cool, and it explains why Freeplay doesn’t want to make the
recent hack of the PSP Go public (the exploit is still useful
for hackers as it allows to run unsigned code on the PSPGo, and
therefore analyze its firmware more precisely). It also explains
why we should now be
