Are phone emulators allowed, or does it matter if I use an emulator on my phone or on a PC or even on a different device?

Most phone based emulators are banned by almost every NES game on the board. They are typically very inaccurate emulators by Speedrun standards.

These are the posted Emulator Rules for Galaga. After review, The Moderator in me would say, "Avoid the cell phone and try to get a PC recording if possible." But I am not a Moderator for this game, so my judgement means little against what the mods here feel. :O

Include Emulator and version used in submission notes.

• Mesen, Bizhawk/NEShawk, puNES, Nestopia and FCEUX are the most acceptable emulators, listed in order of accuracy, most other emulators are not accepted. Retroarch should not be used.
• It is preferred that the entire emulator window is captured, to help prove the emulator being used.
• Recommended to use input display, frame counter and have “No Movie” showing to help prove legitimacy.
• RAM and memory watch features are not allowed, as they provide an unfair advantage that is not possible on console.
• Remapping buttons during a run is not allowed.
• Mapping multiple buttons to one key is not allowed.
• Rewind features not allowed.
• Submitting a movie file or a recording of a movie file playing not allowed.

Hey, sorry for the slow response, but I agree with everything SchmidttyGames listed above. The boards for classic console games that allow phone emulation are few and far between due to accuracy issues. I inherited the board after the rules above were set, but the emulation direction above is a pretty common standard for any NES platform speedruns.
