I found a copy of flyable heart on rutracker, but when trying to run it the font is garbled and after clicking OK on the textbox at 1:21 in this video nothing happens. Nothing useful in the log. I'm not sure whether the crack (I think one is included?) or wine is having a problem with it. I think you'd probably be a lot more of an expert in this area than I am, unfortunately.

Ah, yes, you do need to configure WINE to display Japanese characters before you can run most Japanese visual novels.

You'll want to make sure ja_JP.UTF-8 is uncommented in /etc/locale.gen and that you've run locale-gen afterward. You also need some Japanese fonts installed to display the characters: https://wiki.archlinux.org/title/Localization/Japanese#Fonts

Use LC_ALL=ja_JP.UTF-8 when invoking wine.

That's probably all you need at a basic level to get characters displayed, but there's a more complete setup here: https://learnjapanese.moe/vn-linux/

Yes, I suppose this is somewhat obscure. Oh well - I can get the DMM games working in a Windows virtual machine, and most visual novels run slow, but otherwise mostly fine without dedicated graphics.
