I know fnes and gpengine have rf support in the works. Apparently black the author of gpengine has come up with a way to add wireless support to his emulator. I imagine in the future we will see some emulators released which will take advantage of this. Just think about it you and a friend sitting on oposite sides of an airplane or bus playing contra with eachother. Thats pretty damn impressive if you ask me. If I were going to the UK gp32 meet I would do my best to get ahold of an rf unit or two and then contact ryle and see if you could get a beta of fnes. I know he has given them out to a few people and if you ask nicely he might allow you guys to play with it at the meet.
