I wonder if Skateboarder is XaviX or some unSP thing like some of the Jakks ones then, if it's 16-bit data bus it's probably not like these 6502 ones, should still be interesting tho.
Guess the pieces will start to come together once the roms are dumped :-)
Frogger will be NES VT derived, it's almost certainly the standalone version of the game in the vgtablet, but released 2 years earlier without the other games or the fancy menus etc.
Seems like there are more different techs involved here than first anticipated, but as this is all new discovery / research that's no bad thing anyway.
(speaking of the unSP driver, batmantv and walle probably shouldn't be clones of vii, and vii probably shouldn't be marked as working considering at least half of the games in it just give you a black screen)
