What's the problem? Describe what went wrong.

When choosing a different option in Gamecube controller port 1 than what I recorded the .dtm replay with, the replay quickly desyncs.

What steps will reproduce the problem?

Choose "standard controller" for port 1 and record a single lap in a Grand Prix in Double Dash, then play back the replay with port 1 set to "GameCube Adapter for Wii U". The replay will only play correctly if the same option was chosen in port 1 (in this example, standard controller). You can also record with the adapter first and play back with a standard controller for the same result. If the replay was originally made with 4 players, I believe changing what is in the other ports can also mess up the replay. I tested with Smash Bros. Brawl as well, and same problem there.

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

Yes, it's in 5.0-9751.

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 first saw this issue in 5.0-9494, while it doesn't seem to be present in 5.0-9492.
