Classic Player Deluxe 86 in 1 is a homebrew multicart specifically parodying bootleg ones, made by forgotusername. It's not really a true bootleg. https://archive.org/details/86in1

I'm not sure if Bully Boy is homebrew. It uses a multicart system used by actual bootlegs, but anyone can use that these days. The fact that the name is a credible (if poor) translation of 霸王小子 (Bàwáng Xiǎozi; I would translate it as "Conqueror Kid") doesn't help.

It's probably more accurate to just say Bootleg Games? A lot of them aren't even from China, they're from Taiwan. Also, not all of them are from plug-n-plays; I don't think the Miwi BS9800 is a plug-n-play at least.
