Version 2.7.6 on Win11. The error I get when selecting YakuHigh from the game list is "Update error: Couldn't find pdz file main.pdz"
Aha, interesting! Well, that piece of information got me thinking that I might be able to use WSL to spin up the Linux build of the simulator, and that does seem to work! :D
EDIT: I'll need to contend with the lack of keyboard remapping in the simulator for flipped screen, but I think I'll be able to find a workaround with AutoHotKey or similar. :)
