I wanted to see if it was possible getting VS Balloon Fight to play on a standard NES (at least in 1-player mode). Here's how far I've come:
* The game "boots". Press START to insert coins and SELECT to start the game
* Currently converted to MMC1, horizontal mirroring.
* Palette is currently not correctly patched, w.i.p.
However, I can't get control of the player. I've patched all $4016 & $4017 writes and adapted them for the NES but can't still get the player to move, and I've tried alot of things.
Some kind of guess is that it might be IRQ-related since there's no second CPU to trigger these, but it's a wild guess. Or it might be some other obvious bug I currently can't see. :)
So, if there's any skilled ROM-hackers here, feel free to check this out. If you've got any ideas about how to get things working, feel free to share ideas, credit will be given. :)

I've attached the IPS below, use it to patch a ROM with CRC32: ff89eddd

Apologies for the necrobump, but I think this would be pretty great to have on real NES hardware, considering it's upcoming Switch release and the history of it being developed by a different team than Satoru Iwata's.

VS Mach Rider would be pretty cool as well, considering it has a few extras over the NES original :)
