Hey guys, i was just wondering if u guys experience the same problem as i do. I use nebula for kof 2002 and mame special edition for 2003 and i cant do Super Desperation moves Its not that i cant input the directions and buttons for it, its just that when i press the 2 buttons eg A + C they dont register... it only does the desperation move. I cant seem to do 2 buttons at once. i have tryed using the hotkeys as well, but that didnt work for me ethier. Does anyone else experience this? If anyone knows a solution please reply Thanks, V1p3R
