I just tried installing the latest GOG versions of BRUSA (2.0.0.9) and FJ (2.0.0.4) under Wine on my burly Linux workstation (Ubuntu 15.04 64-bit, NVidia graphics with proprietary binary-blob driver). My results below.
The good news:
FJ played 100% correctly--graphics, sound, gameplay, music, everything. No foolin'. I dialed it up to max everything settings and it Just Worked.
BRUSA gameplay and graphics were all correct.
The bad news:
Sound on BRUSA doesn't work at all. It's garbled; it sounds like techno played by an Atari 2600.
The typematic rate on the setup menus is crazy fast. You tap the up/down key and it zooms up and down at lightspeed; when you release it lands on a random option.
Anyone know a fix for the typematic rate on the menus, or to make sound work for BRUSA?
