What's the problem? Describe what went wrong.
When I make a replay using the Gamecube adapter, it doesn't play back correctly.
What steps will reproduce the problem?
Start a game of Double Dash with controller port 1 set to Gamecube adapter for Wii U with the other ports turned off. Do a lap on a GP, and then play back the input, which should desync well before the first lap is finished. In Smash Bros. Melee, it would desync while I changed the difficulty level and life count before even starting classic mode. I didn't have any problems with replays made using a standard controller instead of the GC adapter.
Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.
It's present in 5.0-10413.
Is the issue present in the latest stable version?
Not in 5.0
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.)
This first shows up in 5.0-10202, while it's not a problem in 5.0-10200.
I have attached a sample replay for Double Dash that I made with the GC adapter on 5.0-10202. The replay ends at the end of the first lap in a GP. Note that although I can't play it back correctly on the version I recorded it with, this will play back correctly on 5.0-10200, assuming buttons aren't pressed on the controller during playback, because 5.0-10200 allows input during playback, unlike 5.0-10202 which fixed that issue. The replay won't work even on 5.0-10200 if port 1 isn't set to Gamecube adapter before starting the replay.

Does the replay I uploaded work for you? I made a new folder with portable.txt and tried again with 5.0-10202, which can't play it back correctly, but it worked with 5.0-10200.

No, I just created and played an input recording myself, as per your steps to reproduce. It didn't desync, so there must be some issue on your end.

Does the following replay work? I created a new folder of 5.0-10413 with portable.txt and only turned off the Wii remote, switched port 1 to GC adapter, set my path and turned off the memory card. Everything else, I left at default. Note that although I couldn't get this replay to work on 5.0-10413, it did work on 5.0-10200.

There is a weird bug associated with GameCube Adapters for Wii U if no controllers are plugged in and haven't been plugged in since Dolphin start... maybe that's the issue?
Updated by SuperDavid over 5 years ago
This is the first time I heard of that bug, but I don't think that's the problem. With the replay "ddashtest 5.0-10413.dtm", I just discovered that it won't play back correctly on 5.0-10200 if the controller in port 1 is unplugged from the adapter, but that still doesn't change that I can get the replay working (if the controller is plugged in) on 5.0-10200 but can't get it working no matter what on 5.0-10413, the version I recorded it with.

Actually, I'll need to more carefully compare it, but when I play it on 5.0-10200 with the controller unplugged, it seems to play back the same way as it does on 5.0-10413 with the controller plugged in. I'll compare them both side by side to be sure.

Playing back the replay on 5.0-10200 with the controller unplugged from the adapter is an exact match with playing it back on 5.0-10413 with the controller plugged in. However, controllers plugged or unplugged, I have not been able to make any replay of Double Dash with the GC adapter on 5.0-10413 that doesn't desync.

Okay, I'm able to reproduce this only if I make an input recording from boot. It does not happen if I start recording after booting game. It must have something to do with GC adapter initialization.

Sorry, I always record from boot. I forgot to make a note of that.
