I was wondering what emulators are allowed in this community? I use Snes9x, but I also use OpenEmu on mac.

I see that you ran Lttp. It actually has emulator rules on its leaderboard.

I'll paste em here:

"1) Allowed emulators are SNES9X (v.1.5 and later) and BSNES (including higan/byuu)"

"2) Front ends such as Retroarch and BizHawk are allowed, but additional restrictions apply (No RunAhead on RetroArch, etc.)"

These seem pretty easy to understand and follow. I was aware that SNES9X was allowed but only certain versions of it and I couldn't remember which versions.

So yeah, stick with SNES9X (run on the right version obviously). I'm not sure about OpenEmu, so I'd suggest avoiding using that for the time being.
