MarsSeed [1] filed a deletion request for lib32-libsidplay [2]: This Commodore64 SID music file playback library was last updated in 2004. It was used through gstreamer via one of its "ugly plugins". Repo dropped the 64-bit package recently due to "failing to build" (FS#78686; no details specified or logs shared). As of today, AUR's lib32-gst-plugins-ugly has also removed this dependency. Irrespective of the viability of the 64-bit build, this lib32 package is emphatically not needed. By following the dependency graph in Arch and AUR repos, one can see that the only consumers of lib32-gstreamer are wine packages, and its commercial alternative, crossover. There is hardly any bin32 media player in the whole ecosystem. (And there's no reason for such to exist in x86_64 land.) Emulators of Commode 64 et al never needed libsidplay, as they implement full emulation internally, including the waveform generator of the original SID chip of Commodore machines. As for applications external to Arch/AUR packages, I can hardly think of any that would need this niche, extremely old library either directly or through lib32-gstreamer. So I conclude that it's safe to delete this package from here. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/lib32-libsidplay/
