You see I have an EZ Flash 3-in-1 for my DS Lite. It lets me load GBA roms from the Slot 1 storage onto it and play them on the Lite.

As you can see, it's a half-tall cart so it sits flush with a DS Lite. However, on the old DS, any variation of the GBA, or the GameBoy Player for Gamecube, it cannot reach the contact pins inside without removing the plastic shell of the systems. I'd really like to be able to play these GBA roms on my Gameboy Player. I've confirmed that its compatible when I removed the plastic shell of the GB Player. It works fine. But when everything is put together, of course it cant reach.
So did anyone ever make a cheap extension bracket that hooks onto the cart and makes it as tall as a normal GBA cart? Either that, or I may just take a dremel tool to the GB Player and carve out a chunk of the shell so it can shove on in deep enough to connect.
