So when does the game actually copy the save files back to disc? If it never happens because they are corrupted then I guess this is only a temporary corruption, which would be a nice coincidence.
What happens if you hit reset in the emulator after the game returns to the title screen, is the corruption still there? I admit I haven't looked at the SRAM code in FDS in quite a long time so I'm not familiar exactly with what it's doing.
The game saves after the credits are fully played out. After that, it saves the data to disk and returns to the title screen. So if you reset before that, it's fine.

I just did some testing to check where the save corruption happens, and it happens when you spawn in the glitched town.
I reached that town, then went to the bottom floor and died in the water until I got a game over. Selected the bottom option (save & quit) and all save slots were corrupted.
Then I made the eye death boost be a game over and save & quit before the game spawned me in town. And it did not corrupt the saves.
Seems as if, as long as we appear in the glitched white town, the saves will corrupt the next time you save.

1. In fact, Burb's testrun on Bizhawk 2.2.2 doesn't feature such heavy graphical corruption either. I don't know exactly what caused those lines to appear in my run, but my best guess is that this is because I entered the glitch world during day time since I skipped the day-night transition, while all those RTA runs enter the glitch world during the horrible night.
Yes, the extra graphical corruption is exclusive to it being daytime after the warp. The same thing happens on everdrive if you do the transition glitch.

I'll add that after the wrong warp on the eye enemy where you end up in the glitched town and do a floor drop from within the wall, you do a screen scroll/transition before the camera catches up to you. This will put you under the intended screen and kill you (a quirk that exists in the NES version as well)
The game will then respawn you at the last ground tile you touched. The magic here is that in between these two screens in addition to just a normal loading screen there's also a disk swap happening. So when the game attempts to put you back in town it glitches further and puts you in a glitched map just under the bridge to Dracula's castle. At least that's what I think is going on.
I found this by pure luck as I was curious where it would respawn you if you did that. Luckily for us, it was a location of great benefit.
