Im fine with dumps and skeletons, means we know it's secured.
I bet these are the same hw as the radica skateboarding
These are XaxiX hardware, which is more advanced.
You can tell because both show the XaviX logo on startup (which I'm guessing was a legal requirement to use their development kits / hardware or something, as it's always the same)
XaviX is probably closer to a SNES, there's a lot more going on in the games with multiple scrolling planes, a lot more animations etc. It's a more powerful system.
I'm not ruling out there being multiple generations of XaviX hardware either (because the quality of the games seems to differ greatly) but none of the ones I've emulated so far have been XaviX, and it seems very unlikely Skateboarder will be. Feature-wise Skaterboarder looks closest to Golden Tee, single x/y scrolling plane with sprites above it.
The non-functioning Taito Nostalgia driver in MAME is the only XaviX dump we have (if it's even complete) and it's not plain 6502, it's currently hooked up to the SNES cpu, although I don't know if anybody verified that to be correct, or if it was just closer.
*edit* Peter points out that there are 3 generations of XaviX
the original XaviX which is a custom 6502 @ 21 Mhz SuperXaviX, which is a custom 65816 @ 43 MHz and XaviX-2 which is some '98Mhz RISC processor'
So I guess the Taito Nostalgia one we have dumped is 'Super XaviX' I guess, because it seems closest to the 65816. The other Snowboarder one there might be the original XaviX instead because it looks kinda basic. None of the ones we've tackled so far have had XaviX logos tho.
my gut feeling is the ones we have been looking at might be 'pre-XaviX', developed by the same people, before they settled on a standard (but I have no proof of this)
