As long as you're fine with FMVs missing in ZX, then everything else is working perfectly.
I undubbed the ZX games, installed HD textures for cutscenes and patched the EXE so English names would show up in the Japanese ZX games. Source: https://steamcommunity.com/sharedfiles/filedetails/?id=2008335805
The Zero games play flawlessly and the menu of the collection itself works perfectly as well, however the ZX games' FMVs don't play (not with default Proton, not with Proton GE, not with mf-install). Therefore the ZX games are flawed as they are right now.
Proton-7.1-GE-2 GloriousEggroll
Used Proton-7.1-GE-2. Tried installing various things such as LAVfilters through Protontricks in order to try and get the cutscenes to play, but that didn't change anything. Attempted to install devenum, quartz and wmp9 as well, but I'd get an error 5 each time at quartz.
Cutscenes still don't seem to work in the ZX games using Proton-7.1-GE-2.
Though the cutscenes are still not fixed, the performance regression introduced in Proton 6 seems to be gone now.
mf-installcab
Use Proton 6.3-8, and run this for mf-installcab: PROTON="$HOME/.local/share/Steam/steamapps/common/Proton 6.3" WINEPREFIX="$HOME/.local/share/Steam/compatdata/999020/pfx" ./install-mf-64.sh -proton
mf-installcab
Cutscenes missing in ZX/ZXA
I forgot to add this, you'll also need (in addition to mfplat.dll) to add the following 3 .dll files to the same directory as the one MZZXLC.exe is located in: wmasf.dll, mfperfhelper.dll and wmvcore.dll.
