Me and my friend built an arcade machine a few weeks ago, installed an ordinary PC with latest version of MAME, and connected the keyboard curcuit to 2 8-way arcade joysticks. We also added support for coin insertion, player start etc. with special keys. A trackball is working as our mouse and can also be used with some games.(posted 9883 days ago)This whole project turned out to be the most addictive machine I have ever seen! Its just about as close you get without actually playing the real arcade. All my recordings from now on will be done using this arcade machine :)..
