Neogeo pocket color emulator?

hows it kickin fellas, ive been playing alot of snk vs capcom: motm on the neopop ngpc emulator, and its alot of fun. been playing alot of ss!2 on it also. my question lies in the multiplayer component of the emulator. How can i play with my brother or friends ? we have separate computers, and ive tried linking up, but. . . it constantly says connection failed when i try and link up. . . i dont know what im doing wrong or not, but could someone plz give me a somewhat thorough set of instructions on how to get it to be playable in multiplayer ??? and if there is a better alternative, plz say so.
