Are mobile emulators allowed?

yes i think

Per the leaderboard rules--

Allowed Emulators:
Preferred: Project64 v1.6.x
Alternate: OpenEmu
Alternate: Mupen64Plus

All other emulators and versions (such as Mupen64 and Project64 v1.7 & v2.0+) are banned. Using a Mupen64Plus core within RetroArch is different from vanilla Mupen64Plus and is banned. Any ROM modifications or emulator settings that cause non-vanilla behavior are banned (e.g. widescreen)

mobile emulators are not allowed

Short answer: mobile emu=banned, I remember asking if an emulator was allowed since it was the vanilla experience but on mobile and the answer was "its a mobile emulator so no" even if it was literally a official nintendo emulator ported on mobile (which we all know wouldn’t happen) they’d still ban it. I guess they’re scared of getting their wr stolen by a dude on his iphone.

I mean no one is stopping you from running on mobile... You just can't submit to the boards.
