This is a library mod for computer mods. It provides a pure Java implementation of a RISC-V Virtual Machine and a bootable image.
This is a separate library mod due to its size. It is expected to change quite infrequently, as opposed to mods using this library, so this saves everyone quite a bit of bandwidth and disk space.
There are no user-facing changes when this mod is added on its own.
The main consumer of this library mod is OpenComputers II. Here are some screenshots of Sedna running in OpenComputers II.
