The Game Box 400 in 1 (2022 PCB) is using the 42xx type tech, like the 2019 PCB version, making the 2020 PCB version the odd one out. Maybe some of these are actually knock-offs on different tech (or they just used whatever was available at the time)

ROM is different, but menus etc. look basically the same, so I haven't checked what's actually changed (maybe a few game substitutions?)

Apart from the Master System / Game Gear clone, these all boot anyway. I'm quite surprised none of these were duplicates as they all looked basically the same as already dumped units, however they're different PCB revisions with different encryption schemes etc. (and maybe a few games swapped out)
