Notes
1 For compatibility with existing software, the suffix returned by Wimp_ReadSysInfo 2 does not take into account whether alpha-masked sprites are in use or not. E.g. if alpha-masked sprites are in use then instead of returning an “A2” suffix it will just return “22”. Software which wishes to use different sprites if alpha-masking is supported should either query the feature directly using Wimp_ReadSysInfo 29, or rely on calls such as Wimp_Extend (sprite suffix) to locate the correct sprite file to use.
