Platform: Arcade

Dottori-Kun, a 1991 demake of Sega's 1979 maze game Head-On, was created not to be played, but rather as a legal loophole around Japan's Electrical Appliance and Material Control Law which claimed that all arcade machines must contain a game when sold. Dottori-Kun allowed Sega to sell generic Astro City arcade machines which the arcade owner could swap the contents of at their leisure, and included test features to ensure the machine worked properly before installing a proper game. The game did not support coin insertion, and therefore was not a viable option for arcades even if an owner believed there was an audience for its simplistic gameplay and graphics, leading to the board being scrapped most of the time.

In 2018, rapper Soulja Boy attempted to sell his own line of video game consoles, called the SouljaGame line, sold for $149.99 for a console and $99.99 for a handheld. Advertising claimed that the consoles would be compatible with a variety of consoles' games, including modern platforms like the PlayStation Vita, Nintendo 3DS, and Nintendo Switch. They obviously did not have such compatibility, and were rather a generic retro emulator console one could find on small business-oriented retail websites such as Wish and AliExpress loaded with pirated and modified games sold at a markup. Game libraries featured included the Neo Geo, NES, SNES, Game Boy, Game Boy Color, Game Boy Advance, Sega Genesis, Sega Master System, Sega Game Gear, and PlayStation. The only difference from these pre-existing consoles is a photograph of Soulja Boy printed onto the box. He would eventually stop selling SouljaGame consoles, with the website for the console redirecting to Nintendo's 3DS website.
