Question from Adam: I’m the same guy you called about the Street Fighter 2 World Warrior game. I just bought this Street Fighter 2 game in a Defender cabinet for $100. I was able to fix the vertical collapse with one of your awesome videos. Now I want to upgrade the ROMs because it would be nice to have a few more characters to play with. When I worked in an arcade in the 90’s we would get the ROMs and replace them in the boards, but I can’t remember if it worked for the original Street Fighter 2 game or not. By searching eBay for ‘Street Fighter chip’ I can find people selling them but I would rather not waste time and money on random purchases if it wont work at all.

Here is one of the eBay listings: http://www.ebay.com/itm/street-fighter-2-champion-chip-lot-capcom-used-untested-arcade-game-parts-c1m-1-/151372875535?pt=LH_DefaultDomain_0&hash=item233e86c70f.

Any help would be awesome. Thanks, Adam
