Some notes about cRSID usage in Rockbox
by Ninja (Wolfram Sang) in 2023
The cRSID codebase is from v1.0. The only change made was a separation of the
cRSID header into a public and private one, so it could be compiled as a
library. You can find it as a separate commit in the git repository. This
likely needs to be updated whenever a newer version of cRSID shall be used.
Currently, newer versions of cRSID are available but they have been discarded.
v1.1 mainly adds a high quality playback mode using 7x oversampling. This is
too much for a Sansa Clip. Because the old playback mode still exists, it might
be possible to add a runtime option to let the user choose. As a first step
however, it was decided to give the user a working codec without having to deal
with options. v1.2 mainly adds a SDL-based GUI player, no bigger changes in SID
emulation. Staying with v1.0 also keeps the codec size significantly lower
(~50KB for v1.0 vs ~90KB for v1.2 on the Sansa Clip).
