From what I’ve seen, you’ll need to download the unofficial patch and install it using Protontricks (available on the Discover store).

• Run protontricks
• select VTMB (it may not show up if it’s on a microSD, you’ll either need to use flatseal (from Discover) to let protontricks access your microSD or move the game to internal storage
• select the default wineprefix
• Run explorer
• Navigated the files to the Z: drive and locate your downloads folder or where ever you downloaded the patch
• Run the patch and install as normal

After that, run the game with the launch options: -full -width 1280 -height 800 -game Unofficial_Patch

Unfortunately, I don’t own the game, so I can’t promise this is all working. Some guides from a year ago have been updated to say they’re broken now. If you do all that but the game isn’t working well, try older versions of Proton (Mostly 6 & 7) and see if they work any better.
