Extra Hard Mid Boss
I made a port of the TNKernel real-time kernel to the Saturn, available on GitHub. The kernel is released under a BSD license.
The kernel does not support SMP, but you can run separate instances on both CPUs. API documentation is available on the TNKernel website, the small API changes made should be obvious. You can configure which vectors are used by the kernel in the file tn_port_config.h, and interrupt handlers should be wrapped by the macro found in tn_port_asm.h. I'll post a working example project soon.
Note that the port hasn't been very thoroughly tested, so expect bugs.
