cemu-linux's Issues

Issue with installation of wine, winecfg, launching CEMU and Launching BOTW

Hi!
As promised I will detail the issues I uncovered following this guide. Most of which I managed to work around with some googling, but I will detail them nonetheless since it could be useful to other people.

Anyhow, the first bug occurred at the "sudo apt-get update" part:

Get:1 https://dl.winehq.org/wine-builds/ubuntu bionic InRelease [6 257 B]

N: Updating from such a repository can't be done securely, and is therefore disabled by default.

I googled and found a line on stackoverflow that worked:
wget -nc https://dl.winehq.org/wine-builds/winehq.key && sudo apt-key add winehq.key && sudo apt update

2ND issue occurred when launching winecfg:

wine: created the configuration directory '/home/USER/.wine'

Wine asked me to install Mono and gecko and I did so when prompted. That made winecfg work

Third issue occurred when launching Cemu:

It launched Cemu but these warnings are nonetheless worrying.
I tested if wine was properly installed by running "wine notepad", and that worked.

The next issue is the one which bothers me the most, because I haven't been able to fix it, and it doesn't let me play BOTW.

After having launched Cemu with the aforementioned error log, and after having installed BOTW E and C packages, I tried launching the .RPX file for BOTW. Cemu was then filled with a black screen alluding to the game launching (also updating the title to "Loading...") .That was not the case. After a few, perhaps 10, seconds, Cemu crashed with the following error.

wine: Unhandled page fault on read access to 0xffffffffffffffff at address 0x7bc58c7c (thread 0037), starting debugger...
Segmentation fault (core dumped)
Can't attach process 002a: error 5

I went to the internet and someone hinted to the fact that it might be trying to run a 64 bit program in 32 bit . I exported Wine to 64BIT (found another guide that did this) and then tried again. Now nothing would happen after launching BOTW. Not even a crash.

Hopefully you can help me with the last bit, because I think the other things are installed in such a way that it should work. It's just that cemu & Wine don't seem to mix very well.

Followed instructions exactly.

jstest-gtk is outdated and should not be used

Wine use SDL2 to handle joysticks, which also use new joysticks subsystem on linux. jstest-gtk is configuring an old one and will be useless at best and harmful at worst.

Sadly, there are no good calibration tools for new subsystem besides using evdev-joystick with evdev, which require some skills. Anyways, jstest-gtk is not useful.

GamePad view is black

Hello, so I just recently tried this tutorial out to play Super Mario 3D World on my laptop. It works really well, but there is an issue. For some reason, the GamePad screen isn't displaying anything. Any ideas?
