OK, that fills in one of the questions I've had regarding those boards' initial POST behaviour and is actually kinda cool. A bit bass-ackwards IMHO - they could have just loaded pre-generated save states from storage into RAM rather than creating them on the fly at each boot - but I guess that doing it that way saved $0.17 per board on the BOM or something

Given the intended application of these boards, it makes sense: with near-instantaneous game switching being desirable, this would certainly be one way of achieving it.

I seem to recall someone mentioning several years ago that there was an in-game giveaway in one of the 39-in-1's games as to the boards' MAME origins. Specifics escape me right now, but I want to say that it was something along the lines of a later-fixed bug specific to MAME's emulation of that particular game being triggered in one of the drivers during gameplay; this at least pegged it to a MAME version less than n.

That said, it's a pretty weak memory. I could be confusing it with something else.
