Okay, it's very, very close to working.
The RM2K Font Patch just installs two fonts to the windows/fonts folder, so it doesn't have to be a post-dependency.
Ahriman's Prophecy.tie is correctly installing the fonts and MDX9 Legacy, then the game itself. But if you run the game right away, with winewrapper.exe still running, the virtual desktop setting will be ignored (which might mess up your desktop), and the new fonts will not be detected.
If you wait a bit for winewrapper.exe to die, but before winedevice.exe does, and run the game, the virtual desktop will show up, but the fonts will still be "missing."
Finally, if you wait until both winewrapper.exe and winedevice.exe end, and then run the game, it looks perfect.
It does not matter if both the game and the patch ask for the bottle to be rebooted or not.
Is there a setting for killing those wine processes?
