Looking at Zauf's most recent run (congrats on the sub btw) it looks like Zauf is using v1.10. I just installed patch 1207 for Re-Volt which adds compatability with Win10, a functioning soundtrack for all tracks and 1080p support. Seeing as there are so many advantages to 1207 I think it's ok to use this patch seeing as the gameplay is exactly the same. Same for the (nearly nonexistent) loadtimes.
Yeah I don't think there is any difference between the patches. I'm pretty sure they all work the same
Yeah the AI is pretty good on 1207. But I also feel like the physics are somewhat different. It's just a feeling though, most of the stuff I usually do doesn't work as well as it should. That could also be my imagination though.
I haven't tried a different version than the 1.10, I'll definitely take a look into 1207 if others use it to make it even, if there would be a clear advantage due to the difference in AI
I wouldn't call it an advantage. It's a two sided blade. The fact that the AI is in your neck at some times can screw you over yes. But the same thing can help you get a faster time. (mainly lucky firework/waterbomb boosts if you stick the landing or them pushing you in front of them when they have a battery running)
So far we allowed all versions used for runs, whether it was v1.10, v1.20 or the 1207 patch.
How about RVGL? Edit: I just realised it's been used before, so I assume it is in fact allowed.
