Sporting a newly downgraded PSP and looking for things to do with it? We're talking about apps that need kernel access that only 1.0 or 1.5 PSPs can bring. Well, there's a new beta of the NesterJ NES emulator that features -- get this -- WiFi network play (adhoc only). In addition to letting you rock multiplayer NES games (we're thinking of you, Contra), it's a great sign of the sort of thing we could expect from other retro-upgrades. How about WiFi multiplayer in the Wii virtual console? How about some of those 7000 PSone games rocking WiFi multiplayer support?
