• I downloaded a new version of Dolphin (4.0-5811 to be specific)
• I renamed a few Folders containing the extracted files from various Dolphin downloads
• I "Browse"d a couple of my Memory Cards in the apparently infamous Memcard Manager. Just to be clear, when I say "Memcard Manager", I mean "Tools">"Memcard Manager (GC)" in Dolphin
  
  (NOTE: Yes, this one seems the most likely and I did NOT see the warning at the top of the window before doing so. I'm fairly certain I didn't do anything to the actual saves, I just viewed them by hitting "Browse" and only went as far as to highlight a single save if I remember correctly)
• I used a patching program to downgrade my Brawl 1.02 ISO to version 1.00 so that I could create a Project M 3.6 Beta ISO with the correct md5 checksum
• I then proceeded to create the Project M ISO and play it before finding that my 20XX Save had been corrupted
  

• Out of the 4 separate .raw files (the USA and EUR files of both GC Folders), ONLY the USA .raw file in the first GC Folder and the EUR .raw file from the second GC Folder seem to have NOT been corrupt.
  
  This means that I still have a useless Melee save with almost nothing unlocked on the USA file, and a Paper Mario: TTYD and barely started Mario Sunshine on the EUR file.
  
  This is fortunate because my Paper Mario: TTYD save is safe on the EUR file, which I mostly care about.
  
  On the other hand, this isn't so great because I lost my LoZ: Wind Waker save which I spent a bunch of time on, but don't care for nearly as much as Paper Mario.
• I'm pretty sure I viewed all 4 .raw files in Memcard Manager, so I'm not sure why two of them got corrupted and two didn't
• I did already look online for some solutions and from what I gathered, corrupted saves should still be view able in Memcard Manager? I'm not sure about this one, but either way, the saves I lost have completely disappeared it seems. (See my next post for the reason)

http://garteal.hostoi.com/fixing-corrupt-save-games-in-dolphin/

This is probably outdated, but the person writing the article could still see his or her corrupted save in Memcard Manager, and the saves that I'm looking for in my Memory Card aren't there anymore.

If anyone can offer any insight at all as to what the most common causes of memory card corruption are, that would be much appreciated! It would be even better if someone has heard of a fix!

I can say however, unless you actually copyto/delete from a memorycard, there is no modification done to the file.

All reported issues with the memory card manager have been solved, I am not aware of any conditions (excepting power failure/reboot during write/ other issues outside of the program) that would result in corruption. If there were, I would attempt to fix them, in fact anyone who comes across this post, PLEASE report reproducible issues with the memorycard manager to the issue tracker as well as directly to me via PM.

Ancient versions of dolphin would fail to copy the gameid to some memory region, causing all saves to start with 6 nil bytes.
This was not a problem until the time that dolphin started to write the gameid to that memory region,
you see, these bytes are used to identify which saves belong to a particular game, before it appeared that all saves were for that game, and so it could find the correct one by 'filename'.

Once these bytes were correctly written, a game would say, give me all the saves on this card which belong to me
returning every save that matches the gameid, however 000000 was written from before, so the save was no longer 'owned' by that game.

On the remote chance that something goes wrong, create a new card for each region in the memorycardmanager, and merge the saves for that region to the new card

o.0 I swear, I did not let any of the games reformat the cards and I'm positive of that. I did test all of my GameCube games to see if they all wanted to reformat the cards, but then I would just immediately stop the game when the corruption message came up. This is why I said "Disappeared" in the title because according to that outdated article on fixing corrupted Memory Cards, you could still see the data, it just wouldn't work or something. In fact, I know that I still haven't reformatted the Memory Cards because they still state that they are corrupted.

That's what I figured, thanks.
