Create dedicated zpool for wine stuff and link that to ~/.wine.
Install winetricks and use that for tuning. Install required / missing
components. Use gl and vulkan render. Switch system settings to use
all built-in modules.

Make snapshots, or just wipe all when not working, fear not, just
don't link ~/.wine/drive_c or ~/.wine/drive_d until all works fine and
you know how it works. It's not really straightforward but I made it
somehow there so you can :-)

I even made RMT (windoze only Raster Music Tracker for 8-bit Atari) working.

Your friends are:
winetricks
wine winecfg
wine control
wine expolorer

Have fun :-)
