Crocomire's Last Stand by Roebloz answers that question by putting you in control of the SA-X itself in an alternate timeline where the X have wiped out the last of the Space Pirates and now set their sights on Crocomire, sealed in the Dissolvery behind four Security Locks. A full redesign of the Zero Mission map built from the ground up, the hack pulls tilesets from both Super Metroid and Custom cartridge, plug and play. Compatible: GBA, GBA SP, DS, DS Lite.
