I did some checking and it seems Kaillera is dead, dead, dead. to bad. before your time Will we used to have a dedicated Kaillera server. It was good times. I seem to remember we had a few hosted tournies. and there were always site regulars on the server. as for alternatives. I don't think there is anything on Mame but a hacked p2p Kaillera. Most emulation gaming is going on GGPO and Supercade (used to be 2DF, I believe) both use custom emulators. I know GGPO's is based on Final Burn Alpha http://ggpo.net/ http://supercade.net/ I've played on GGPO and it is about the best netcode you'll find anywhere. but it only supports a handful of games. I never did try supercade. but it looks like it supports alot of games. Last time I played GGPO you could not make custom private rooms. so that is a downside. Maybe they updated it.
