BitBuilt - Giving Life to Old Consoles

but why?

The gba cart shell as usb is actually a really cool idea

But why not? Set a custom theme for PM to make it all Gamecube like(yes, I am aware it would be alot of work there as well). And laugh as someone tries to call dibs on first player

I've seen people make flash drives out of GBC carts before, so I didn't think it would be too much of a stretch
