Most of these are old homebrew apps that were originally coded many years ago for the PS2 (back when that scene was lit like PS4 4.05 is now), so now that PS4 can run these PS2 apps and emulators using the built-in ps2emu developers are re-releasing them as PKG's for 4.05 users.There are hundreds of old-school PS2 homebrew apps, many are simple games but there are also some cool emulators etc so while we probably won't be doing news posts for every one (as the flood begins) hopefully a PS2 homebrew PKG pack will arrive so a compilation post can be done at some point.
