The feeling when a proprietary non-replaceable essential part in a $250 custom arcade stick breaks is not a good one. It is now the most expensive paper weight I've ever owned.
It's an arcade stick for the Wii and the part is the cable that connects the stick's control board to the Wii remote. Sadly MadCatz decided to make a very unique cord for it and they don't offer replacements.
I keep wanting to tell you to solder some wires, But I'm sure you've though of that...Hell maybe you could make an Atari joystick out of that mess...Or use the case for something else...
