PSP gets its own homebrew online gaming network, outweighs Sony's own efforts
Sony made much ado of the PSP's position as one of the first online gaming consoles, but unless your idea of online play involves Skype calls, there hasn't been a lot to go on since 2004. Team PRO is addressing that deficit through Prometheus, a completely community-driven rival to PSN. The hack lets PSP games with support for ad hoc WiFi play go online by wrapping the normal local-only multiplayer in an emulator library that broadcasts to other Prometheus players. It requires a second-generation or newer PSP as well as a wireless router that can expose the PSP in DMZ mode, but there's a live who's-playing board and even an in-game chat mode to coordinate that round of Fat Princess as it happens. Of course, using a wholly separate gaming network outside of Sony's rubric involves a whole lot of warranty-voiding risk; if you're willing to live on the edge, though, Internet games of Metal Gear Solid: Peace Walker or Pro Evolution Soccer 2012 will let you put off that possible PlayStation Vita purchase for a little longer.
