These are untouched Japanese VOD rips. The video quality is really bad, most of these dubs are cropped to widescreen, and the streaming rips have Japanese hardsubs. Fist of the North Star's compilation dub has the video edited to change the mouth flaps, so it won't be easy to reconstruct these with a better video source, no idea about the other ones.
These have some very minor glitches, at least in Fist of the North Star and Lun Lun, that might, or might not, be present in other sources.
Thanks to fabrebatalla18 for providing these rips.
