I need 6 or 8 at max (Incase if i wanted to set some hotkeys),And yes they are customizable.
A full keyboard will be perfect because i change buttons according to what am playing. Like in street fighter games there is 3 punch buttons and 3 kicks so i set (A,S,D,F..Z,X,C,V..where F,V are hotkeys) but in games like king of fighters there is only 2 for each so i set the buttons beside each others (A,D..Z,X,C,V..where A,D are hotkeys)
However,A number pad like this
wont be such a bad idea actually,But i'll keep it as my last desperate solution if every thing else failed.
