Well, just letting people know if they are like me and have an updated PSP for whatever reason that we can now use homebrew.
An exploit was found with Lumines that involves a buffer overflow like the one in GTA. I won't post any links because most sites are seedy and talk about nefarious things, which we would not dare to mention here, no we wouldn't.
Anyways, the only homebrew at the moment for this exploit is a "Hello World" demo, but a downgrader to should be coming soon.
Commence speaking of legal homebrew and nifty things that us folks without a homebrew capable PSP can look forward to.
