The Game won't start at all, unless you install .NET 4.0 Framewrok, which can be done by installing winetricks and protontricks.
Once done, just type on the Terminal:
$ python3 protontricks 393540 dotnet40
Once installed .NET 4.0, the game launcher starts, and it works as expected.
Reproduction
Just click Play, and after some seconds, nothing happens.
Final Remarks
This game is actually a licensed PlayStation Game sold along a custom fork of the Libretto PCSX emulator, along a .NET program that works as a configuration tool and launcher.
The game's vendor displays the GPL code on their Support Page, so there's no GPL violations.
And also the forked emulator works without the copyrighted PS1 firmware, that Sony would never license it outside the PlayStation Store games!
