Symptoms

The following issues apply for both The Legend of Heroes: Trails of Cold Steel and The Legend of Heroes: Trails of Cold Steel II:

• When installing the game from the steam launcher, it tries to install MS .NET 4.0 (for cold steel I) / .NET 4.7 (for cold steel II). This break the game and make them unable to launch. In fact you get the same error as reported here : https://github.com/ValveSoftware/Proton/issues/1048 . To launch the game, you have to use wine-mono
• The intro video is not displayed (the sound plays but the video is a black screen). This is a case of a missing video codec. Installing k-lite codec pack MEGA in the prefix and disabling winegstreamer fix the issue for me.

The following issues apply for The Legend of Heroes: Trails of Cold Steel II only:

• It need protontricks 748490 quartz to start without crashing
• When starting a new game, the player is asked to load a save from the previous game (The Legend of Heroes: Trails of Cold Steel). The game cannot find the save as the save path is not shared between prefixes. The location of the game saves are inside steamapps/compatdata/748490/pfx/drive_c/users/steamuser/Saved Games/Falcom/... .This could be fixed by making the 'Saved Games' folder a symlink to a folder inside the home folder in the same way as wine does for desktop/my documents/my music/etc.

Once these issues have been addressed, it will be possible to mark this series as platinum on protondb as both games work perfectly from the start to the end if they manage to start.

Reproduction

Try to launch the game after downloading it from the steam app.

Start by reproducing the launch failure from the Steam launcher with Proton and inspect the reported prefix path, steamapps/compatdata/748490/pfx/drive_c/users/steamuser/Saved Games/Falcom/. Check the wine-mono, codec, quartz, and shared-save requirements described in the report; done means Trails of Cold Steel II launches and can load the previous game's save without those manual workarounds.
