Gameboy Advance AA Battery Tray Divider

The GBA funnyplaying precut shells do not have the battery tray divider in place for the purpose of using a rechargeable battery pack. It'll still work with AA batteries, but a slight bump or jarring motion can knock the lower AA battery off-kilter just enough that it no longer makes contact. It'll either reset or completely turn off the gameboy. This simple divider can be placed between the AA batteries on it's own, or stuck in place with double sided tape.
