We haven't seen the guy who made Dolphin splits in one and a half years.
If a runner wants them to work it's now upto the runners discretion to get them working. None of the mods besides Roofress run Dolphin, and it's not really Roo's responsibility to get them functioning again.
"For use with the Dolphin emulator. Works with 4.0.2 and 5.0 releases. (direct download)"
If you're using any specific revisions but Dolphin 4.0.2 or 5.0, that's why it isn't working.
I've looked at the dolphin script before and it's a complete mess. That's partly down to the way dolphin stores it's data but SG also has a very different way of making scripts to the rest of us.
I've seen it fully working so no reason for it not to work now. If it somehow is broken though it won't be fixed
Door 71 on Claire A PC probably doesn't work because you're going through the save room door, which is slower, as opposed to going through the door at the back of the room (crow hallway) and using the locked door directly ahead of this door to go down to where you use the Heart Key.
Slower routes aren't gonna be accommodated for, obviously.
The all doors splits, Supergamer's included, take into account that the player is familiar with the most optimal route.
The splits do work though. If they don't, can you post a video of where the splits stop functioning properly?
The all doors splits are set up with a very specific route in mind, the fastest route... basically. 71 just happens to be at a point where a diversion is possible that will cause the splits to stop functioning. If you're taking the long way around after Chief Irons, as in, going through the safe room > down the ladder and so forth... then that is why the splits no longer work after door 70.
For Supergamer's splits to work properly, use Dolphin 4.0.2. We cannot guarantee any other version will work properly with those splits.
