>>715544618 (OP)They barely even started. Also no, they're still making them, IIRC there's some new NeoGeo one that just came out too.
The biggest reason why companies don't make more of these things is primarily licensing.
Like, how are you supposed to get the license to add [game] to the system when the company that made [game] has been merged and sold off five times since the 90s? Or said game had licensed music in it that you'd have to go get the rights to redistribute again.
Plus, making one-off hardware like this is generally kinda iffy in the first place and I'm damn sure these companies are just shitting together something from some no-name factory in China anyway.
I dunno, anyone with a third of a brain is just going to buy some Anbernic or a Retroid Pocket, or an Everdrive on a real console or something and not bother with buying some overpriced mini console with 7 games on it.
