Holy fuck, 10 years later, and I'm finally ready to start tackling this project. I just dug the controller out, and thank God I took the batteries out when I stored it. I found it, put in some new batteries, plugged it in and it still works great. Still wondering the best way to convert this to AC voltage. I'm assuming a wall wart would work? these things take four AA batteries at 6V. I've got dummy batteries connected to a power cord in my Pacman and I'm not real happy with the way that works. I'd much rather have a direct solder option. I'm just wondering where to solder the two ends of the power cord to. I don't wanna take this apart unless I know it's possible.
