Fightcade is basically a match-making program, a lobby for fight game enthusiasts. On the backend it uses an emulator called FBA, which was designed to run MAME games (actual ports of arcade games). It also uses a different technology to play P2P (GGPO), one that is supposed to be easier to set-up (no issues with routers, and no need to port forward).
Recently it has been updated/upgraded to Fightcade 2, which promises many enhancements, specifically the addition of Sega Genesis emulation.
On the reddit page for this project (it is in BETA as of Oct 27), I found a copy of the supported roms.
NHLPA93, NHL 94-98 were all there, not to mention NBA Jam, Madden etc..
As it is in beta, it can only be tested by folks with older accounts (you need to register to play on Fightcade).
Anyone here a member of Fightcade since 2014? We need a tester!
