SFA3 and Marvel Vs. Games (4 Player) Questions

[kobebryant24]

im currently running mameplusplus .119. i have the 3 marvel vs games and their "4 players for kaillera" versions. i also have sfa3.

 

 

my first question regards sfa3. i read on this forum that there is a hack to play a 2 on 2 battle. how do i do that? the only thing i can do is play a dramatic (2 vs 1) and reverse dramatic (1 vs 2) battle. how would i play a 2 vs 2 battle?

 

my second question reguards the marvel vs games.

->how does this mode work exactly? can it be 3 players and cpu or is 4 players REQUIRED to play this mode?

->how would p3 and p4 join (inserting coins)? is this mode p1&p3 vs p2&p4? who does the tagging?

->does this mode only work in kaillera online play? i tried inserting coins playing offline with p3 and p4 but that did not do anything.
