Feels about time to establish proper emulation rules, I myself plan to submit runs in the very near future. If you're unaware of what's generally allowed, check Contra III leaderboard. I'm also gonna include this

Likewise if you check CV4 which is much more popular and competitive than this game generally. You can spot "ZSNES (all versions) and SNES9X (1.43 and below) are banned."

Allowed emulators should be: BizHawk/Lsnes/Higan

snes9x 1.53 and above is pretty universally accepted for one, I recommend reaching out to more well established snes communities if mods are unaware of the current general standard.
