1Some notes about cRSID usage in Rockbox
2by Ninja (Wolfram Sang) in 2023

4The cRSID codebase is from v1.0. The only change made was a separation of the
5cRSID header into a public and private one, so it could be compiled as a
6library. You can find it as a separate commit in the git repository. This
7likely needs to be updated whenever a newer version of cRSID shall be used.

9Currently, newer versions of cRSID are available but they have been discarded.
10v1.1 mainly adds a high quality playback mode using 7x oversampling. This is
11too much for a Sansa Clip. Because the old playback mode still exists, it might
12be possible to add a runtime option to let the user choose. As a first step
13however, it was decided to give the user a working codec without having to deal
14with options. v1.2 mainly adds a SDL-based GUI player, no bigger changes in SID
15emulation. Staying with v1.0 also keeps the codec size significantly lower
16(~50KB for v1.0 vs ~90KB for v1.2 on the Sansa Clip).
