Description:

Problem:
The online functionality of Cemu does not work on Linux, although it runs on Windows. I have made several attempts to resolve the issue, but so far, without success.

Operating System: Linux [Flatpak version]

Expected Behavior:
The online functionality should work the same way on Linux as it does on Windows. Online features should be accessible without issues.

Please fix!

Are you sure you put your files in the right locations?

Yes, I tried it the same way on Linux like I tried it on Windows. Windows accepts the keys in the settings, Linux doesn't

Most of the files should be in your mlc, and seeprom.bin and otp.bin belong in ~/.var/app/info.cemu.Cemu/data/Cemu

I just said I already did. I just tried the Windows version with wine, the files get detected. Only the Linux builds version doesn't work.

@PaperTobi I'm having the same issue, but with the Cemu AppImage. After using strace to see what files were accessed, I see that Cemu is only looking in ~/.local/share/Cemu for seeprom.bin and otp.bin, not the actual Cemu install dir. Strangely, the mlc01 file lookups DO use the actual Cemu install dir:

newfstatat(AT_FDCWD, "/home/flotwig/.local/share/Cemu/otp.bin", 0x7ffd90faf8f0, 0) = -1 ENOENT (No such file or directory)
newfstatat(AT_FDCWD, "/home/flotwig/.local/share/Cemu/seeprom.bin", 0x7ffd90faf8f0, 0) = -1 ENOENT (No such file or directory)
newfstatat(AT_FDCWD, "/var/opt/Cemu/mlc01/sys/title/0005001b/10054000/content/ccerts/WIIU_COMMON_1_RSA_KEY.aes", {st_mode=S_IFREG|0644, st_size=1200, ...}, 0) = 0
newfstatat(AT_FDCWD, "/var/opt/Cemu/mlc01/sys/title/0005001b/10054000/content/ccerts/WIIU_COMMON_1_RSA_KEY.aes", {st_mode=S_IFREG|0644, st_size=1200, ...}, 0) = 0
newfstatat(AT_FDCWD, "/var/opt/Cemu/mlc01/sys/title/0005001b/10054000/content/ccerts/WIIU_ACCOUNT_1_RSA_KEY.aes", {st_mode=S_IFREG|0644, st_size=1200, ...}, 0) = 0
newfstatat(AT_FDCWD, "/var/opt/Cemu/mlc01/sys/title/0005001b/10054000/content/ccerts/WIIU_ACCOUNT_1_RSA_KEY.aes", {st_mode=S_IFREG|0644, st_size=1200, ...}, 0) = 0
newfstatat(AT_FDCWD, "/var/opt/Cemu/mlc01/sys/title/0005001b/10054000/content/ccerts/WIIU_OLIVE_1_RSA_KEY.aes", {st_mode=S_IFREG|0644, st_size=1200, ...}, 0) = 0

Looks like a bug here, since it doesn't work as documented in the Online Play docs or the error message ("x.bin missing in Cemu root directory"). As a workaround, put your 2 .bin files in ~/.local/share/Cemu instead of the Cemu root directory.
