- kospvr - This is the hardware-accelerated Dreamcast backend
- software - This is a stub software rasterizer used for testing testing and debugging
To compile for Dreamcast, you'll want to do something like the following:

For a release build, replace the cmake line with with the following:

You will need KallistiOS compiled and configured (e.g. the KOS_BASE environment
variable must be set)
