Error while trying to open raw memory card file in memory card manager

[SMWiz]

I used GCMM on a homebrewed Wii to dump raw copies of physical memory cards to an SD card and moved those files to my computer. I opened the Dolphin > Tools > Memory Card Manager to try moving some save locked games between cards (like Animal Crossing and F-Zero GX). The 59 block and 251 block cards opened just fine. The 1019 memory card threw an error.

I was using v5.0, so I updated to version 5.0-13963 to see if that would fix things. I'm still getting an error when trying to open the raw file. The error reads, "Failed opening memory card: Filesize header mismatches actual card size. Invalid checksums. Data in area of file that should be unused."

The card works when I insert it in my GameCube, so the card is not corrupted. I'm trying to figure out what I can do to get the data on this card accessible in Dolphin. Any help is greatly appreciated. Thank you.

Dolphin version 5.0-13963

Have you tried exporting the save files as gci exports in GCMM, and then importing them into Dolphin's memory card using the Memory Card Manager?

That did the trick! Thank you so much, KHg8m3r! This has been driving me up the wall.

Can you post the card that is detected as corrupted but works on hardware so we can adjust our checks in Dolphin?
