2600RGB version 1 info archive.

How to use

The extra button mounted on the joystick can activate three functions.

• Extra + Up = Select
• Extra + Down = Reset
• Extra + Fire = Palette switch

The palette switch may also be a second button mounted on the Atari. The palette switch performs different functions depending on how long you hold the button down.

• 0-0.4 seconds = Pause toggle. A quick tap of the button will pause/unpause the console. Because this is a hardware pause of the CPU, the video signal will cut out while the console is paused.
• 0.4-2.5 seconds = Select next palette.
• 2.5-10 seconds = Select palette #1.
• 10-20 seconds = Automatic PAL/NTSC game detect toggle. Enabled by default. This will allow only the selection of PAL palettes for PAL games and NTSC palettes for NTSC games. It uses the refresh rate to determine the game type. This should be disabled to play PAL60 homebrew games with correct colours.
• 20-30 seconds = Pause enable/disable toggle. Disabled by default. The pause feature may be annoying for some people so it is disabled by default.
• Hold the palette switch while powering on the console to enable/disable the 2600RGB board. When disabled, the original RF output will work as usual but there will be no video output from the 2600RGB board.
