$ sudo dnf install wine wine-alsa wine-mono winetricks
Create a 32-bit wine environment for sdvx:
$ export WINEARCH=win32 WINEPREFIX=~/.wine.sdvx
$ winetricks dotnet48
It is good idea to take a snapshot of the environment because you would end up reinstalling sdvx to copies of the same environment multiple times.
$ tar czf .wine.sdvx.tar.gz .wine.sdvx
Run sdvx installer:
$ wine sv3c_installer_2018082900.exe
The installation may randomly fail. Retry and it will succeed eventually.
Start sdvx launcher:
$ wine start 'c:\users\Public\Desktop\SOUND VOLTEX III.lnk'
User authentication randomly fails. Restart the launcher and repeat authentication until it succeeds. Sometimes it takes dozen(s) of times, but it will succeed.
First play of each music fails after ~10s of delay reporting download failure. Retry and it will succeed.
Monthly update always fails. Reinstall sdvx to a new copy of the wine environment and run update in the new environment.
$ mv .wine.sdvx .wine.sdvx.old
$ tar xf .wine.sdvx.tar.gz
$ wine sv3c_installer_2018082900.exe
You can transfer music cache in the old installation to the new one:
$ cp -r ~/.wine.sdvx.old/drive_c/ProgramData/KONAMI/eacloud/SOUND*/MusicData ~/.wine.sdvx/drive_c/ProgramData/KONAMI/eacloud/SOUND*/
Do not try to reverse engineer the music data. Be a good citizen. Doing bad things on linux can lead to more aggressive protections against non-standard installs that would make playing sdvx on linux harder or even impossible.
Try tuning pulseaudio settings:
$ sudo vi /etc/pulse/daemon.conf
Add these lines:
default-fragments = 5
default-fragment-size-msec = 2
