I've found a lot of 4-6in, 1 out switches, and I currently have an automatic 4 in, 1 out switch at home. However, I'm working on setting up a gameroom that I hope to end up with about 22 consoles. These switches must exist, but I have no idea how to search for them since I'm probably talking a commercial solution. Most retro video game systems use standard RGB, and anything else that is newer, I'll have to have a separate solution for.
Anyone have any suggestions on where to start??
