NOTES:

- Hardware: Gaelco CG-1V/GAE1


VIDEO HARDWARE NOTES:

- The CG-1V works with 16x16, 5 bpp gfx. It can handle: 2x 1024x512 tilemaps with linescroll and 2x banks of 512 sprites (sprites can be grouped up to 16x16). Sprites can make the background darker or brighter.

- Some games have two RGB outputs to allow two or four simultaneous players linking two cabinets (World Rally 2, Touch & Go). In 2 monitors mode, the hardware maps one tilemap to a monitor and the other tilemap to the other monitor. The game palette is splitted, using the first half for one monitor and the second half for the other monitor. The sprite RAM has one bit that selects the sprite's target monitor. The sound is splitted too, right channel for cabinet 1 and the left channel for the other cabinet.
