Emulator

What's the problem? Describe what went wrong.

Recording input and then playing it back corrupts the savefile of the game you recorded the input on(unless it's a gamecube game).
I have tested this on Super Mario 64 (NAAE01), Mario Kart Wii (RMCE01) and Super Mario Sunshine (GMSE01). Sunshine's save file was fine. SM64 and MKW's were not.

Replaying the Input recording in wx also corrupts the savefile.

What steps will reproduce the problem?

1.Start a Wii/VC game
2.Create a savefile
3.record an input sequence
4.stop the game and play the input sequence back
5.Restart the game.

Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.

5.0-7827

Is the issue present in the latest stable version?

No.

Atleast it doesn't tell me on 5.0 that the Wii system menu has been damaged when i boot up the game (in this case Super Mario 64(VC) NAAE01)
I don't know if the system memory is actually fine.

If the issue isn't present in the latest stable version, which is the first broken version? (You can find the first broken version by bisecting. Windows users can use the tool https://forums.dolphin-emu.org/Thread-green-notice-development-thread-unofficial-dolphin-bisection-tool-for-finding-broken-builds and anyone who is building Dolphin on their own can use git bisect.)

I can bisect the issue if necessary.
