Make game playable online

There is a game called SSF2 0.9b, previously able to be played online but the servers were taken down. Would like the game to be made playable online again between two people, without having to put servers back up. Some key points: -This is a downloadable Adobe Flash Player game -Controls should be able to overlap for player 1 and 2, i.e. each player's controls should be considered independent keyboards/ controllers -There should be minimal lag when playing online -If at all possible, there should be a buffer option to adjust for lag, similar to the one found in screenshot uploaded (taken from Dolphin Emulator Netplay). -Alternatively, if possible, if the game could somehow be ported to Dolphin Emulator then this would be ideal, although I'm not sure this is even possible
