Robot room? I have no recollection of any bugs in BG&E at all.
The patch for Anox really did help a lot, but it still isn't perfect. Julia claims she couldn't get it to run properly on XP (which it did before on 2 other systems). I haven't yet tried it. She says after she plays a while the screen wigs out.
It's this room where you have to knock some robots around to hit a button. Once you do and the door opens, it's suppsoed to drop a keycard. When I run to pick up the keycard my character just falls through the ground. There's no way to get the card. I think the bug may have only been in one version of the game (European release maybe?).
Anachronox was awesome. I never experienced any serious issues with it. Back when I used to play it on my Voodoo card I used an OpenGL driver called WickedGL. It boosted OpenGL quality and performance amazingly! I played the game again a few months ago and it seemed to work fine. The biggest issue everyone has with Anachronox is the OpenGL.
ATi messed up the old OpenGL drivers, so now even Quake 2 (any Quake 2 engine game [incl. Anachronox]) runs at a pretty crappy framerate (24-30 fps). I managed to exctract the OpenGL driver from Catalyst 4.11 (the last good OpenGL), and the I overwrote the current one I ahd at the time, and Quake 2's framerate went back to 80+ fps! Then I remember when Catalyst 6 came out that trick stopped working, and I had to live with whatever OpenGL driver ATi gave me with the latest release.
