An early prototype of an unreleased port of Metal Slug: Super Vehicle-001 for the Nintendo Game Boy Advance. It was announced to have been cancelled due to cart size limitations. Stages can be completed by pressing Select.

This prototype originates from two developer carts. One of the carts produced a bad dump (tthe first $20000 bytes are null, then there's null corrupt bytes at $30000 that go to $40000 or so, then every $1000 bytes after that until $50000 is corrupt too), but seems identical to the functioning cart. The archive includes both ROMs.
