If you haven’t upgraded your PSP’s firmware beyond 1.50, your patience has just been rewarded!
DevHook 0.44 was just released – it now lets you emulate *every* firmware version (including the latest, 2.71) on your 1.5 PSP. You’re actually using 1.5 to ‘run’ 2.71 as if it were a standalone app. It sounds crazy, but it works flawlessly.
Now there’s literally *nothing* that can’t be run on a PSP with firmware 1.50. Homebrew emulators, UMDs, ISOs of UMDs, you name it.
