Perfect System got updated.
https://astromuseum.org/sonicZone/perfectsystem/sonicperfectsystem
>Updated to Sonic Perfect System Collection: BLACK LABEL.
>Removed sections for Sonic 1/2/CD RSDK Decompilations and Sonic 3 A.I.R. I no longer use the former, and the modding community for the latter keeps imploding. Just use Ultrafix.
>Re-Translated mods moved to 'Optional' across the board.
>Replaced Sonic Adventure Re-Translated with a newer mod using an updated translation.
>Sonic Unleashed section updated with new mod selection.
>Added Shadow Generations.
