Sonic the Hedgehog 2 v0.9.20

Correct native foreground sprite ordering, Knuckles wall-push poses and glide contact/recovery. Restore save selection when rewinding back to the menu, preserve controller input through character adapters, extend original water-surface artwork across wider views and center custom-character act-clear headings.

Fresh launcher settings use Fit to screen; saved aspect, mod and input choices are preserved.
