i have used both the 60 in and 1 and the game elf 412 in one vertical games. Overall the game elf 412 is probably the better unit. Some things don't emulate as well on the 412 game elf as the 60 in 1 like Congo Bongo. But other games emulate surprisingly well for the complexity of the games. Lots of duplicate bootleg titles on the 412 like "puckman" vs pacman.

Creating a simple MAME setup out of an old PC was better than both the 60 in 1 and 412 in 1. I wheeled the arcade cabinet into the laundry room and put the mame display as a wall mount tv and tank stick controls on a simple stand I built.

I have a game elf vertical 412 in 1 on a 37” screen. It’s great for some of the shumps like Raiden and dodonpachi. Pac man works well, although I’m not a pro and couldn’t tell you faults even if they’re there. There are LOTS of crap games that you probably won’t have any interest in, I think I have my list trimmed down to 100-150 decent games. Some of the games are emulated well but they need specific controls, so they’re removed from my game list as well.

No Major Havoc or Black Tiger, no thanks.

I have one of the game elf 412-1 and agree it has its limits. But when I have people over they enjoy it, and it allows me to capitalize my pin space!
Once you've whittle down the games that either don't play correct or are just duplicates it's a good multicade option.
