I would call them a failure, quite the opposite really... I would say they are a huge success, at least finicially. That doesnt mean I support them, but I dont hate them either.
As I've said in other threads, the biggest "issue" I have with arcade 1ups is the fan base itself. Why? Because I really dont understand it, it just doesnt make sense to me. Let me elaborate...
I have been following the arcade 1up community rather closely (I watch youtubers that only talk about them and am in the FB group). They have developed a "us vs them" approach, perhaps MAME builders have propagated that as well?
Anyways, I just watch a video where one of these arcade 1 up youtubers bought a gameroom solutions kit. He actually really liked it and called it a "level up from arcade 1 up." He would NOT say it was better than arcade 1 up, but you could tell he liked it better. He just said things like "both are really good options." In the comment section though... I read TONS of comments like this "I like arcade 1 up better" "I'll only buy arcade 1 up" etc. So they have developed a pretty loyal fanbase, and that's what I dont understand? For casual gamers, sure I get it. But for people to buy ALL of them, mod them, etc. You are spending a lot of money for an inferior product. You can buy a kit for the same price, and itll be WAY better. That's what I dont understand.
