Lxdream – an emulator for the Sega Dreamcast system, running on Linux and OS X. While it is still in heavy development (and many features are buggy or unimplemented), it is capable of running most demos and some games.
The target system is a 3.0Ghz Pentium 4 with a GeForce FX 5 series or equivalent. Current performance with those specs normally ranges from 50-100% depending on load, but we’re still working on improving it.
Any currently supported Nvidia or ATI hardware should work fine using their supplied drivers. (as in, hardware that’s still supported by its manufacturer) Provided suitable GL driver support was available (and this unfortunately is the big problem at the moment), any hardware capable of providing at least a 24-bit depth buffer should work to some degree.
The last version of Lxdream 0.9.1 was released in 2009.
