This is a pic I put together, it has most every console made worldwide (there's a few I missed)
Including Variations, but not color or minor changes to systems like the buttons, hooks up etc. They gotta look different. Also I saved everyone naming hundreds of pong consoles. Only the first and the changeable Cartridge ones are in this picture.
There's 173 systems in this pic, see how many you can name a few are kinda cheating but are still a console.
Try not to cheat
Sorry about the numbers, some are hard to see, they looked fine before I downloaded it, just do the best you can. And have fun!
