Sonic 2 PN Arcade is a ROM hack of the Sonic 2 Nick Arcade Prototype that tries to make the game feel more complete (kind of ironic because this hack is still a work in progress) and also adding a few new features.

Note: completing Hidden Palace Act 1 will send you straight back to Emerald Hill.

Changes:

• Chemical Plant Act 1 and Hidden Palace Act 1 are completable.
• Palette changes to Emerald Hill and Chemical Plant.
• Spindash from final Sonic 2 has been added.
• Speed cap has been removed.
• Peelout from Sonic CD has been added.
• Sonic 1 title cards have been restored.
• Drums from Sonic 1 Prototype have been added.
• Music from Sonic 2 Final and other Sonic 2 Prototypes have been added.
