Reviving a dead Capcom CPS2 Marvel vs Capcom Arcade Board

Really dig this type of content!

"Capcom CPS2 arcade boards were notorious for permanent failure after the so-called 'suicide battery' that, once had run out, would erase the contents of battery backed up RAM that contains decryption keys for the game. Without this key the board would not run."

I guess that's a thing for "purists" those who have to have the original piece of hardware, collectors, etc. Personally I'd rather have a single system with every game imaginable on it.
