I have the latest release of dolphin (linux). I used https://www.smashladder.com/guides/view/264y/project-m/project-m-netplay-the-sd-method to install project m. The first time I did this it worked perfectly. Then, I tried to downgrade dolphin. I uninstalled the package and built from source, this commit
https://dolphin-emu.org/download/dev/ce493b897d6d3735c930a8465cc0c26bbe5feb86/ . After failing to do that, I completely removed /usr/share/dolphin-emu, /usr/local/share/dolphin-emu, and ~/.dolphin-emu. I removed everything, only keeping the SSBB iso, which I saved by copying to a different folder. Then, I reinstalled the newest dolphin, which worked as intended. While following the exact same guide, I achieved different results. The project m elf launches into an unedited gecko menu, which the guide lists as meaning I misconfigured the virtual sd card. If this is confirmation, gecko gave an error of "no sd card" when I tried to save a configuration. I set up the sd card as stated by guide, with the correct paths and options turned on. Then I tried generating a completly empty virtual sd card to put the project m files into directly, as I had succesfully done prior to finding that guide (I switched because that version was incomplete). Once again, following the wiki's guide on setting up a sd.raw file led to the emulation complaining about the lack of an sd card. I have tried system linking the sd card to ~/.dolphin-emu/Wii/sd.raw (I have ~/.dolphin-emu/Wii set up under paths) and having the actual file sit in ~/.dolphin-emu/Wii but dolphin does not want to recongnize any sd card file it has.
