Rock'n! Monster!!

A puzzle game that was only released in Japan.

ATRC_EN
Located at are two instances of ATRC_EN in the Super Game Boy packet table with bits set  and. Used to disable screensavers for the borders when the bit is set to. Pocket Densha, Animaniacs (Game Boy), and Wario Land II (Game Boy) are the only games that use this feature. Game Genie codes will replace the MASK_EN command with the first instance setting the bit to. Genie codes will enable the second instance setting the bit to. Several borders are loaded in Rock'n Monster, so maybe the developers wanted to disable screensavers since border selections cannot be disabled in the Super Game Boy menu.

ICON_EN
Super Game Boy command packet disables in-game palette and or controller selection schemes which can be disabled by the game developer; however border selection cannot be disabled. Palette disabling would serve games like Uno 2: Small World where custom Super Game Boy palettes are required in order to play. Games never did though they could have overlayed the action window with a custom SNES object or in certain instances where switching away from the intricate palette set would make certain elements of the game look glitched-out or distorted. Disabling controller menu selection schemes could have been used to prevent the player from abusing the A-button and cheating in certain games, or may benefit the player preventing them from skipping over answers in quiz games such as Tokimeki Memorial Pocket: Culture-hen: Komorebi no Melody and Tokimeki Memorial Pocket: Sports-hen: Koutei no Photograph, the only two games that solely disable controller selection schemes. Alternatively, palettes can be set to revert back to the original once changed by using Super Game Boy command packet and bit set to. Rock'n Monster disables palette settings though an additional command with bit set to  exists and is never called or referenced. Game Genie codes will replace the MASK_EN command re-enabling palette settings.
