Battletoads Double Dragon: The Ultimate Team
Developer: Rare Publishers: Tradewest (US), Sony Electronic Publishing (EU) Platform: SNES Released in US: December 1993 Released in EU: July 10, 1994 This game has unused music. This game has a hidden level select.

Just a Battletoads game (essentially Battletoads 3) with the Double Dragon cast tossed in. And many frustrations removed...

Level Select

At the character select screen, press Up, Down, Down, Up, X, B, Y, A. The screen will flash to indicate successful entry. Choose your character to be taken to the level select screen.

Unused Music

The ROM offset 0xB8161-0xB8162 (in both the American and European versions) contains the music ID to be played on the title screen; changing this 16-bit value will change the title screen music. By changing this to 0x0A 0x00, unused music can be heard. In the NES, Genesis, and Game Boy versions of this game, this music was used on the character select screen. In the SNES version, the character select screen instead continues to play the title screen music.
