Memory Card Help

[TheBigJam]

So playing Mario Sunshine, the game was working great except this one chapter which required me to clean an area in a time limit. Even though I cleaned the entire area, it never ended the chapter. After googling the problem, it said my version of Dolphin was outdated. So, I updated my Dolphin to version 4.0.2 and I moved my MemoryCardA to the GC and selected it. Upon opening the game again, it still prompted me as if there was no save file at all. Similarly it happens to my other games. I proceeded to use savestates from the previous version, however that just crashed the emulator. I have no clue what to do.
