Thanks all,
That's kinda how I've figured it. Seems there is a Vs Super Mario Bros (or is it World?) in the arcade, but it came FROM consoles.
It seems all did appear on playchoice-10 and the like, but this is from an era when they put consoles into cabinets for cost savings I assume.
I suppose it could be viewed that way. Though I can't imagine what cost savings they would incur. Some immediate differences was a different PPU scheme necessitating that the arcade versions used a different pallet. Also many (all?) of the arcade versions has additional space to include play instructions. I don't care to play the arcade ports of the console games but IIRC, those games were also tougher (I think Mario had a poisonous mushroom? A feature that wouldn't be introduced until SMB2 (Jap)?)
Also, the PlayChoice-10 cabs are
not the same as the vs. cabs. Each of the hardware had their own versions of the PPU (and then some) preempting most operators attempts to use "cheaper" counterparts from different hardware.
The closest in terms of hardware is probably the PC-10<->NES. With a bit of ROM hacking the PC-10 PPU can be swapped into the NES thus giving the NES RGB output capability. This is somewhat distressing as it seems most PC-10 hardware I've managed to locate has met this ill-choiced fate. There has been some attempt IIRC at creating a daughter card to allow NES carts to play on the PC-10 hardware but this, IMHO, is a rather expensive option.
