The title card for 'Andy Asteroids?' is 'Get Ready' in this prototype.

There are game demos after the title screen.

There is no copyright screen before the title screen.

However, since the SNES version was completed after the Sega Mega Drive version, most of the changes in the prototype are aesthetic, the base game is the same as the final Sega Mega Drive release. A cart with the same exact build not only confirms that the ROM was never modified, but it is infact a prototype of the SNES release since the build date predates the earliest final build date by a few weeks.

This prototype was originally released by the ACCUMULATORS on September 4th 1994 (ACC-EWJ.LZH), but the exact build date and whether or not the dump itself was unmodified was unknown until now.

The game boots immediately to a level select with no other information available.

A direct port of the Game Gear version was also brought to the Master System. This prototype was featured on Season 4 Episode 1 of the show GamesMaster, a British television show that was dedicated to computer and video games. Earthworm Jim is a 1994 run and gun platform game developed by Shiny.
