I'm using the Epic store version of the game via Heroic Game Launcher. It was tricky to get working but once I figured it out it ran perfectly.

After install and before launching the game for the first time;

• Add "WINEARCH=win32" to environment options
• Use GE-Proton7-17
• Launch the game to create a prefix (it will error)
• Use winetricks to install the following Windows components to the prefix;
• xna40
• xact
• d3dcompiler_47
• Use winecfg to add a library override of xactengine3_6
• Goto your Heroic Prefixes directory and create a "pfx" folder inside the rogue legacy prefix folder
• Drag all files from the rogue legacy prefix into the "pfx" folder
• Create a pfx.lock file inside the rogue legacy folder
• Open Heroic Game Launcher and change the prefix directory for rogue legacy to the new "pfx" directory you just created
• Launch the game
