Created attachment 54017 [details] Console output with quartz and amstream
This time no crash. The screen is still black and there is no sound but the Steam overlay is available and pressing escape a couple of times brings up the main menu.
Try running:
$wine Configure.exe
from your Legend of Heroes directory and disable the logo and the opening movie.
I did this with the GOG version of the game and I've been playing the game for about 3 hours now.
