Sonic the Hedgehog 2 v0.9.16

Amy now uses her original half-pipe animation, palette and primary HUD artwork. Solo Amy uses the native one-player role; Amy with Tails retains the native two-player roles. Solo result screens use matching original artwork, and native emerald awards and level returns retain their behavior.

Special-stage palette overrides apply to sprites while native planes retain their ordinary rendering path. Existing world and Shadow palette providers retain their behavior.

Other imported and companion special-stage roles retain their current support limits.
