I resubmitted my old run a couple of weeks ago along with the PC one but it wasn't approved here, was there an issue with it or is this game monitored at all?
OpenLRR is mostly an exact clone with optional cheat and debug features, the one change I can think of that might be an issue is that you can zoom the radar out further by default (e: in 0.0.0.6 onward), which could let players move around a map faster. I don't know if the developer would be willing to make a more speedrun-friendly version or if there's a way to disable that, that might be enough to disqualify it (assuming other players use the radar as much as I do) but with how much the base game crashes I'm hoping there's some way to allow it. Might wanna check it out and see how much of an issue it is. If he fixed the level unlock issue (where only levels on the left side actually unlock to the end) then it'd probably need its own category.
What's the ruling on if OpenLRR is allowed? It fixes the game crashing so much so I could see people wanting to use it, but I'm not sure if it alters things too much to be considered unmodded (it does allow easy cheating but that would be as easy to detect as modded games so I'm not as concerned about that). Also I think the developer has plans to try to fix the level unlock bug in a future release so that would definitely affect any future runs using it. I'd get if it's not allowed but after playing LRR mostly crash-free for so long it'd be hard to go back.
Also on a related note, dgVoodoo's ok right? I dunno how much vsync affects runs but that was already a windowed vs fullscreen issue anyway.
