RP200020

Description:
The Super Game Boy from Nintendo is a cartridge converter which allows Game Boy hand-held games to be played in a SNES console. It is compatible with the original Game Boy cartridges and the early black cased Game Boy Color cartridges. By default it mapped the original four shades of green to various colours on the screen. Some Game Boy cartridges were optimised for the Super Game Boy which allowed access to the SNES hardware and allowed titles to played in 12 colours or have 64 colour border graphics around the game. These enhanced titles had a small "Super Game Boy Game Pak" logo on the box and cartridge. A few games also had enhanced sound and allowed for 2-player using the second SNES controller. Other enhancements too could be found in certain cartridges, for example; Space Invaders which allowed players to access a SNES version of the game as well as a coloured version of the Game Boy game.

The cartridge is essentially made up of Game Boy hardware which uses the I/O of the SNES. As it obtains it's clock from the 21.475MHz SNES system clock and divides by 5, games run at 4.295MHz, which is 2.4% faster than on original Game Boy hardware.

A menu can be accessed by pressing the L and R buttons at the same time, which gives five options:
» Colour Palette: Choice of 32 pre-made colour palettes, the Super Game Boy enhanced palette, or a user-created palette. A few games will not allow the palette to be changed.
» Border: Choose from one of 9 pre-made borders, the Super Game Boy enhanced border, or a user-created border.
» Button Setting: Switches between 2 controller mappings. A few games will not allow the controller setting to be changed.
» Custom Colour: Create a custom colour palette and get a password to retrieve it later. This option unavailable on some games.
» Graffiti: Create a custom border by using several painting tools. If plugged into the second controller port, the SNES Mouse could be used for this feature.
