8Bit Memory, the Etsy merchant who first caught our attention with its external hard drives disguised as NES cartridges, has rolled out another re-use for a proprietary Nintendo storage medium: Game Boy Advance cartridges retrofitted as USB flash drives. They're not cheap -- an 8GB drive is $49.99 -- but they're undeniably cool.

The standard-issue drive comes housed in a Super Mario Advance cart with a key ring and (unfortunately) non-retractable USB connector. 8Bit Memory says it has other games in stock (with more to come) so you can, for instance, request a Metroid Fusion cart instead. We're not sure what it'll do with GameCube and Wii discs, But we'd imagine a Wind Waker desk clock would look mighty nice.
