Sonic Blast (Sega Master System)

Sonic Blast
Developers: Aspect, Tec Toy Publisher: Tec Toy Platform: Sega Master System Released in BR: December 1997 This game has unused code. This game has hidden development-related text. This game has a hidden level select.

The Master System version of Sonic Blast is a lazy port of what's considered one of the worst Sonic games.

That can't be good.

Level Select

Set address D140 to FF at the title screen, then start the game. The Game Gear version's button code is unusable here due to the 1 button serving the same function as Start (starting the game, pausing).

Error Handler

Unsurprisingly, the Master System version of the game contains the same generic error handler as its Game Gear counterpart. The code is identical and just as unlikely to ever actually run.

Unused Text

A leftover build date from the Game Gear version is present at 0xC0:
