Hey guys, i haven't been around here much lately or done much with arcade related anything in a few years. I'm in the process of setting up a newer, faster arcade pc for my 4 player cabinet and i got to thinking about control interfaces. I currently have an ipac 4, which I love and which works great for mame. However when i try to add Steam based fighting games, i frequently run into issues with setting up two player controls. Many of the steam games will not allow more than one player to be assigned to a keyboard. Using virtual xbox360 controller software, i've been able to get work arounds for some of them, but others just don't seem to work.
I'm not opposed to replacing the control interfaces if there are better options out there, but i don't want to spend the money if i'm just trading problems for different ones. Is there a cost effective option that works like an xbox controller? what are you guys using?
