I have this game on Vita, would I post a run as PS?

Under the sub-categories for consoles sometimes I'm seeing PC in N64 (Samwich Any% - Easy)., N64 in PS (spidybawiz 42m 16s Any% - Easy) and PC in N64 again (SamWhich Any% - Hard)

What gives? Clean-up or explanation pls?

This title is available on the NES Classic Mini, I'd like to do a run on said platform rather than an emulator. Can the mods add this? :D

I'd like to submit a run via my Switch but you only have NES and FDS as the platforms.
