ahhh now i see

does this mean i get 2 SBs?

Because the upgrade to Big Sur on my MacBook means I can't play the various imitations of Asteroids, Space Invaders, Tetris, and Pac-Man that I used to play, I'm interested for the first time in a handheld console that can play such games. There are zillions of these things, many of which require considerable setup by the user or are of dubious quality (materials, functionality, etc.). Any recommendations for one under $100? The Evercade looked interesting but doesn't support Tetris (yet, anyway) and apparently has a problematic display.

if you are looking for an emulation handheld the Anbernic rg351p or rg351v are the current standard devices, they differ in small ways but are basically the same in two different form factors. the SD cards they come with are infamous for being bad so you should provide your own, a 128GB is plenty. they can be fiddly to set up but there are plenty of how-to guides out there, and even preconfigured SD card images that you can just copy over and get going.
i have a 351p and it's a great wee device, this site helped me a lot to choose & set up.

Thanks -- I've seen that the Ambernics are admired (and came to that site from YouTube) but am admittedly queasy about the setup despite assurances that it's easy. A lifetime in the Apple ecosystem has probably spoiled me.

Anbernics, that is.
