Hey folks. Amazing to see you actually got hold of some of these medal games!
Yes they are the same HW as Love & Berry: Dress Up And Dance, and the Dinosaur King games. (Mushiking: Beetle Battle used an actual Naomi1 mobo).
Sorry I seem to have missed all the fun - not been on here for many months - I probably could have helped some.
Still got a few system SP / Project Aurora boards here although most of my mini cabs run Jamma now. In the UK we had mostly DinoKing, then LnB, and a few MushiKings. Obviously none of the really crazy KidsMedal titles made it here.
But stuff to look out for.. some of the Japanese cabs (the more red goldfish cab on the right seems to be one) should have stereo speakers in the side plastics, a bit like a Blast City cab!
There are a ton of KidsMedal sports titles that are trackball based... I'd love to get hold of one to make a mini SegaSonic cab!
There is an arcade within the exclusion zone in Fukushima that has a whole bunch of yellow variants of these cabinets - I think they were kids soccer and golf games.
For the CF card - some games are small enough to run direcly from the boot BIOS I understand and don't need a CF card. Love and Berry is one example.
I'll be digging that PCB out soon to get the security pic dumped.
