These covers are for use with the fantastic Wireless Gameboy Controller device by Inside Gadgets. The biggest flaw with the device is that the receiver is just a PCB attached to a plug adapter cable, with heat shrink covering it. Perfectly functional, but a little unsightly. This should fix that.
There are two cosmetic variants--one with a GBA icon engraved on the case, one with a GB icon.
There are two functional variants--thick and thin. For either version, you'll need to trim off the excess heat shrink on the ends of the device.
The thin one is slimmer, but requires a little modification of the receiver. You'll need to cut off the zip tie "knot" from the bottom of the device. Since we're removing the strain releif provided by the zip tie, the case itself is designed to clamp down tight on the cable to provide strain releif. I've only been able to test on the one unit I have with a SNES plug, so it's possible that different receiver types will have different cable thickness. If yours doesn't clamp down nice and tight on the cable, try putting a small piece of electrical tape into the cable channel or around the cable where it clamps in. Uses 3x M3x8mm screws and nuts.
The thicker one is about 5mm thicker because of the zip tie knot, but will fit on the receiver without any additional modification. There is no strain releif on this, since we're not removing the zip tie. Uses 2x M3x10 screws and nuts.
