They are all considered finished games. The footage of Fun Fun Brothers is from from 1997, so it's not from a multicart. It's proto roms on a board or dev board. I wonder about the Block Paradise footage too.So i wonder if its a half finished rom or what the situation is. I also wonder how the video was taken, from a mvs board with the game burned jnto eeproms or if its a rom image in a multicart or something
