This game is very fragile and the setup with wine (I'm using 6.0.2, 32bit) isn't very easy.
After a long time I managed to get it to run on a RPi4 some months ago, but now I have a RPi5 with aarch64 and the fun began anew. With the latest master build, I can't get the game to run: I get an ingame errror message (general protection fault or something).

After some testing I managed to get the game running with older builds (<=0.3.0), but I wanted to get to the bottom of the problem and made a bisect.
And here is the result:

Now, this is only one part of the problem: The game uses Quicktime for its FMV sequences (ugh!). Usually this needs Quickime Light to be installed. But there is an "easier" fix: put the needed library files into the games System folder (attention: the patched QT libraries of this fix are expecting ddwne.dll to be present, which is just a renamed ddraw.dll from wine. I unpatched the files to load the wine build-in ddraw.dll again.)
But from the following commit of box86, the videos get very laggy:

I don't know if this helps you make box86 better, or if the outcome doesn't justify the amount of work you'd have to put into it, but I wanted to tell you anyways.
I love this game and Legend (the company that made it) and I just want to have it running (which I sort of have with box86 0.3.0).

Can you try latest box86 to see if it works better?
