Arcade Classic No. 3: Galaga & Galaxian

MISSION: SPACE SHOOTER

Unused Super Game Boy Features
There are two, and thankfully palette and controller selection were left enabled.

ICON_EN
Game Genie code will replace the PAL01 command with an unused ICON_EN which will disable the ability to change palette and controller settings.

TEST_EN
Game Genie code will replace the PAL23 command with an unused TEST_EN  which will speed the game up to double speed with graphical glitching. This was likely cut because of incompatibility issues with the first Super Game Boy BIOS revision.
