I followed the tips & tricks and forum suggestions to get it sort of working 8.1.4, but suffered repeated crashes.
Under 9.0, it is MUCH more stable. I can run the game in different resolutions now, I can load easily using the load button. A couple of times, I still got a crash, but only when exiting.
I also tracked down the font that was causing the garbled yellow fonts on some of the menus:
lucon.ttf
You need to put this font in the 'fonts' folder under 'windows' in the C drive for the bottle where you put GCII. Fonts will magically clear up. There might still be a little garbling, but nothing major.
