1 | Some notes about cRSID usage in Rockbox | ||
2 | by Ninja (Wolfram Sang) in 2023 | ||
3 | |||
4 | The cRSID codebase is from v1.0. The only change made was a separation of the | ||
5 | cRSID header into a public and private one, so it could be compiled as a | ||
6 | library. You can find it as a separate commit in the git repository. This | ||
7 | likely needs to be updated whenever a newer version of cRSID shall be used. | ||
8 | |||
9 | Currently, newer versions of cRSID are available but they have been discarded. | ||
10 | v1.1 mainly adds a high quality playback mode using 7x oversampling. This is | ||
11 | too much for a Sansa Clip. Because the old playback mode still exists, it might | ||
12 | be possible to add a runtime option to let the user choose. As a first step | ||
13 | however, it was decided to give the user a working codec without having to deal | ||
14 | with options. v1.2 mainly adds a SDL-based GUI player, no bigger changes in SID | ||
15 | emulation. 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). | ||
