This thread will let you know what has been changed for this game, in case you're not in the Sonic Speedrunning discord server.

Added the rule 'Whilst 'with pauses' allows you to pause during the run, unreasonable pauses are discouraged, and may be rejected at the moderators discretion.' to the Level Leaderboard. The mods will go through all the runs and sort them out eventually for you, so need to worry about it.

Addendum added to rules for individual levels: "If submitting a level under Acts 1 or 2 of each zone, submit under "Easy" difficulty. Runs of these levels submitted under "Normal" will be rejected. This does not apply to Boss levels."

This is due to Acts 1 and 2 of each zone not containing any differences in difficulty. Difficulty only applies to boss battles. Due to how the website is structured for handling individual levels, we can only apply Easy and Normal difficulties across all stages, rather than cherry pick the boss levels to only have these difficulty options, while also having separate sub-categories for Sonic and Blaze.

Well technically, you could add duplicate subcategories and then apply those to only the boss levels but I can understand not wanting to do that since it's kinda tedious and a bit confusing for anyone who's not familiar with that.

As of December 17th, 2020, we have made a few changes/clarifications to the rules in order to reflect on the rule changes that have been made within other games in the series on this site.

General Rules:

• Game audio must be present and at an audible level
• Both screens MUST be present and properly stacked to match normal gameplay flow

Emulator Rules:

• DeSmuME and melonDS are the only accepted emulators. Links to the emulators can be found in the resources page.
• The entire window must be present, showing the emulator name and version
• Emulators are not allowed for the All Stories category. Emulator submitted runs are only for individual levels and the All Stages categories
• Frame rate MUST be stable. Moderators reserve the right to reject if run experiences too much slowdown

As for runs that have already been accepted under other emulators or have been accepted without meeting any of the other criteria listed, will be grandfathered in and will not see any changes.
