+The VIDEO CARTRIDGE plugs into the video board, and contains the program roms for the video based game.
Like the MPU4 game card, in some cases an extra OKI sound chip is added to the video board's game card,
as well as extra RAM.
There is a protection chip similar to and replacing the MPU4 Characteriser, which is often fed question
-data to descramble (unknown how it works). In non-question cases, however, the protection chip works

near identically to the original.
No video card schematics ever left the PCB factory, but some decent scans of the board have been made,
