Works fine ootb

Needed Proton 7.x. Neither Proton Experimental nor Proton 8.x would move past an opening black screen.

No Solo funciona en modo ventana a 1280x800
En el lanzador del juego seleccionar modo ventana a máxima resolucion. Juego de GOG.com
Startup - use touchscreen to confirm settings
Some tutorial pop-up text are hard to read on what buttons to press.
Game runs well and the controller works

Runs well with Proton 6.3-4 and WINED3D9
works with:
Proton 6.3-4:
PROTON_USE_WINED3D9=1 optirun %command%
NB! optirun only for use with bumblebee/primus to switch between graphic chipsets.

Get Proton-5.9-GE-8-ST here: https://github.com/GloriousEggroll/proton-ge-custom#installation
The game does black screens for 30 seconds after the matrix intro, before the opening cut scene.
Same with some dialog, the game will seem to freeze until you press [Shift] or [Enter] to continue.

Does not work on Linux - until you tweak things!

I got it running flawlessly using the abovementioned Vulkan / Wine / Proton tweak (first comment).
Now it runs great!
Game starts with a black screen unless you apply a mf-install fix. Below instructions weren't clear enough for me, here's how I managed the game to work:
- Download this https://github.com/z0z0z/mf-install (Code - Download as ZIP)
- Unpack in Flashback's PFX folder, mine was /home/MYUSER/.local/share/Steam/steamapps/compatdata/961620/pfx (change MYUSER folder to your Home name);
- Open terminal, CD to this directory "cd /home/MYUSER/.local/share/Steam/steamapps/compatdata/961620/pfx"
- Run this command in the same terminal "WINEPREFIX="/home/MYUSER/.local/share/Steam/steamapps/compatdata/961620/pfx" ./mf-install.sh" After that a bunch of stuff appears in terminal output, Wine starts and promts to install MONO and some other stuff - click Yes. After that game starts perfectly well from Steam.

Used GloriousEggrolls Proton version with Media Foundation fixes @ https://github.com/GloriousEggroll/proton-ge-custom/releases
On the terminal type:
export WINEPREFIX="/YOUR-PATH-TO-STREAM/steam-library/steamapps/compatdata/961620/pfx"
export PROTON="/YOUR-HOME/.local/share/Steam/steamapps/common/Proton 5.0"
./mf-install.sh -proton

https://github.com/z0z0z/mf-install
Using the above patch above I was able to play the game, once downloaded and extracted run;
WINEPREFIX="/YOUR/STEAM/PATH/steam/steamapps/compatdata/961620/pfx" ./mf-install.sh
Download Media Foundation from here: https://github.com/z0z0z/mf-install/tree/proton
export WINEPREFIX="/steamapps/compatdata/961620/pfx" export PROTON="/steamapps/common/Proton 4.11" ./mf-install.sh -proton

Black screen and nothing happens
Can't reach the main menu, tried installing mfplat and limiting cores, windowed/fullscreen, different resolutions.. but nothing helped.
The config window opens up, but when the game is launched, only a black screen shows and nothing happens.


Black screen when loading. Seems stuck. Setting PROTON_USE_WINED3D11=1 didn't help.

The config window opens, I can choose the resolution etc. But the game doesn't start then, only a black screen is displayed.
