About the speed difference, I don't see any difference between different DOS versions, but at least in the original game the difference between PC and DOS was usually a couple of seconds in the countdown timer, depending on the level.

Anyway, I think HappyTimer has some potential with making the comparison between different versions more fair, as you guys have discussed earlier

Hello! A new runner here. Can't replicate the speed boost from recording on OBS. However, my game sure as hell runs faster than it does in existing runs.

(Edit: I can get 231 in the countdown timer on Go To North, https://streamable.com/s95sw3 which would be borderline impossible with the speed shown in Magic Bong's run for example. There's no way you can save 3 whole seconds there)

Sometimes recording has an opposite effect, though, so the speed isn't exactly consistent even on my own device. (Edit: This applies to v1.3 at least)

In the original game the DOS version seems to be the most consistent, when it comes to running speed. Even though it's substantially faster than the PC version, you can count on it always running at the same speed. The DOS version that every download-site seems to offer has the Christmas Edition in it, so I wonder if allowing runs on DOS, like in the original game, would make any sense?

That's a good idea. It would help a lot in my opinion.

Nights is a good idea. I'm not a big Nights fan but it wouldn't be bad at all to race at. Also, as you suggested 1-7, I think it's the best to start at.

Not a bad idea, even though I think it would be more simple to post them on the "official SRB2 Records tracker". There's no yet place to discuss the records there though. This site could fix it, I guess?

I guess there's almost as big changes as there was between 2.0 and 2.1... At least I've heard of many Deep Sea and Arid Canyon changes. Many other are rather surprise. For example, at least I didn't know about the new Techo Hill 2 in 2.1 before release. Anyway, at least we can hope SS will do better than the shorter record attack records. Not going to stop submitting. ;)

I think the category should be saved because it takes a lot of time to do a run there. At least it's my opinion since I like to watch runs even from 1.09.4 nowadays. But still, have you seen what happened to 2.0.5 - 2.0.7 time-attack records when 2.1 came out, or even heard about them? There's understandably no list of them anymore since not many actually cared about them anymore. I guess there won't be a huge difference when 2.2 comes.
