http://arx-libertatis.org/https://github.com/arx/ArxLibertatisDeveloped by Arkane (Looking Glass) Studios.
Arx Libertatis is mainly developed on Windows and Linux, but has also been successfully run under Mac OS X and FreeBSD.
original requirements:
500 MHz Intel Pentium CPU, 64 MB RAM, 16 MB video card RAM, 4X CD-ROM drive, DirectX 8.0, 750 MB available hard disk space, Windows 95/98/2000/ME/XP (WIN)
It was also released for XBOX 1 (not sure if that source is available)
From my understanding the textures and sounds can be compressed/downsized to fit dreamcast's memory limitations.
Or is a port completely impossible?
What do some developers think?
