Note: waterbear is an assembler/disassembler for the Dreamcast VMU.
The first release of waterbear is out! Note that v0.1.0-v0.1.4 are all throwaway releases. They were just me trying to figure out how to get Travis CI to deploy the binaries to the GitHub releases section.
It's still very bare-bones at this point, but I've tested it on various existing VMU assembly sources, and compared the output to the output of Marcus Comstedt's assembler. It appears to be working correctly, at least for the most part.
