Using Proton GE 7-31 the game appears to function without issue, minus the audio of the opening. Audio can be restored by modifying GE 7-31
Using versions later than GE 7-31, I experience frequent crashes and issues, with the game crashing every time I attempted to load a game. With versions earlier than this one, the opening video would not play at all. With this version, I am yet to encounter any crashes or freezes, and the opening video plays, although without sound. By removing libprotonmediaconverter.so from lib, not lib64, the audio will also play with the opening. I have not encountered any issues from making this change, although I have not gotten very far and cannot verify that it will not cause any. With all of these changes, the game seems to function without any issues or missing features.
works with Proton 6.3-8
verified but unplayable due to crash
game is guaranteed to crash when moving cursor to bottom menu. regardless of proton compatibility, with or without. l tried both patched and no patch and is still crashed.
crash when entering option
Tried installing lavfilters with protontricks
lavfilters
Opening video not working
I tried installing lavfilters with protontricks but it did not fix the opening not playing
Mapped back butttons L4 and R4 to mouse keys
40hz refresh rate
Audio of the opening is missing with ProtonGE
Patch can be installed just like on Windows, Opening does play with ProtonGE, but it does not play the audio. With normal Proton the Opening does not play at all and just shows the codec missing screen, OP can be skipped with just clicking on the screen.
