Are you kidding me?  Buy a $150 game system, hack the controls Hahaha... right like thats gonna happen.  Oh wait, I get to hack the VGA cable too ?  Just perfect...
Is there any EASY way to do this?  Damn I really really really want that game.  I am very disappointed  But thanks for the help.

I'm sure you are goofing, but will elaborate.
Sega Dreamcast can be had for $20 from ebgames, gamecrazy, craigslist, eBay,  etc
controllers $5 average price same places listed above.
You can contact Haruman on this forum for pre hacked pads $30 per pair shipped (if memmory serves)
VGA cable $15 eBay possibly other locations as well. snip a wire for output suitable for an arcade monitor.
Search the console section this stuff is there too.
I can snap pics tomorrow after work if you'd like to see pics, but I'm sure there are other examples on this board.
oh yeah Marvel vs Capcom 2 (Dreamcast) = about $10 - $15 and the NAOMI version sells for about $200 - $250 which i'd be willing to sell you.
