There are numerous sites with different projects. It's a lot of fun to see how gamers have overcome their design obstacles. Plus, there is a LOT of self-expression in these different mutations. Let's call them The Mutilators. As each day passes, arcade cabinets are rotting in fields and warehouses.
Machines break and are thrown into dumpsters.
Hell, I've even endured a hornet's sting scavenging for parts while climbing over 30-40 muddy, abandoned cabinets in a barn. Classic cabinets are not renewable resources. They can not be replaced. But there is hope. Just as MAME seeks to document the history of game code, VAPS is attempting to preserve the last physical manifestation of these machines.
