I have uploaded creditless versions of all the 90s Sailor Moon openings! I've also included AI upscaled versions of the OPs. Unfortunately, Toei has not properly cared for the masters of Sailor Moon (not to mention that the 90s anime was broadcast during the SD era, not HD) and as a result the video quality is somewhat poor compared to anime openings you see nowadays.
There have been fan efforts to restore and upgrade footage of Sailor Moon (including the OPs), but I just included videos that were ripped directly/upscaled from ripped videos.
