On this page you will find information about the Two Tigers Dedicated arcade video game. Two Tigers Dedicated has significantly different gameplay from the more commonly found Two Tigers Upgrade, which was designed for a Tron board. The Two Tigers Dedicated romset will not run on a standard MCR2 board without a hardware modification, or a software patch (see below). This web page was started to post all of the known information about Two Tigers, and the MCR class of arcade boardset in general. This knowledge was generated in a quest to create the MCR2 Multigame.
