Contra SNES MSU-1 enhanced 2 player Netplay 60fps 

Technically you are not wrong. But this time, we played the game ported to the Super Nintendo, with the MSU-1 Enhancement (different soundtracks to choose) and some features that are not present in the original (Carry two weapons and the ability to strafe/lock diagonal aiming)

I asked Infidelity about that. He said... *QUOTE* 🤣🤣 who knows, we'll see. *END QUOTE*

Only on the original Japanese Famicom version.

That's the idea.

I can't give any rom links, but you should be able to find out more information if you look up the creator of this rom hack.
