A non-Nintendo release?! This is a prototype of Dune: The Battle for Arrakis by Westwood Studios. Some differences that could be noted are as follows: Missing intro sequence and logo screens, missing options on the titlescreen as well as the “Licensed by Sega” at the bottom, different fonts, missing pieces of music as well as sound effects, and various palette differences. On the “Select your House” screen, the version number is also listed (Ver: 0.03).
