We don't have a discord or whatever to show new skips so here.
You can just barely make that ledge by pressing jump right before J.J. does a sort of falling animation and I think that gives her more height and distance for that jump?
The house skip happened to me when I was randomly mashing start, but it's really inconsistent from what I can tell.
That burn in thing happens sometimes when finishing off a boss with intoner mode and that fire thing doesn't work after a hard knockdown IIRC on actual hardware. If you want a cheap way to record on an actual PS3, you can use composite/S-video output and gvusb2 for $45USD~ which is what I do. You'd want it to be at a low resolution which apparently reduces the lag on actual hardware? I've apparently never played D3 at 720p or higher ¯_(ツ)_/¯
Just to be clear for the NG+ No DLC category, I can use the Bloodstained Garb that you get for upgrading all the weapons right? It seems to allow for multiple chances at doing the weapon swap and infinite dashing glitches
