BP, could you add the OpenBOR-X (BORX) to coinops? Openborx have a lot of good arcade style games, like those: http://www.youtube.com/watch?v=W0rmmklvODM , http://www.youtube.com/watch?v=aBfJfUBSmQw and
there are a lot of games already made for it. I think it would fit perfect in coinops! The openborx (BORX) was made by xport and the source is in xbins (the folder is: /XBOX/Console Based Applications/games/BeatsOfRageX/). cheers!
