Hello. Just stopped by to report a problem with interlaced low-res modes. The Great Giana Sisters screenshot is just an example, I can reproduce this graphics corruption with anything running at 320x512.
Works perfectly with 1.6.1.
Presumably relevant system specs:
. Windows XP Professional SP3
. 256mb NVIDIA GeForce 6800
. 3.6ghz Intel Pentium 4
. 2gb DDR2 RAM
. Latest DirectX and video drivers
