'''Sonic the Hedgehog (NES) - Improvment + Tracks''' is a [[Hacks|ROM hack]] made for Somari for NES. It was first created by the jabu in November 20th 2016. It was then improved upon by Ti and re-released December 1st, 2016. The game play was improved and the sound effects will no longer interrupt the music.

==Changes==
===By the jabu===
*New sprite for Sonic.
*Spin Attack fixed.
*Acceleration of Sonic fixed.
*Centered screen.
*Added animations on some levels.
*If Sonic has 50 rings at the end of the first 2 acts of every zone, he can access the special stage.
*Gain a extra life by obtaining 100 rings.
*New level select screen code: At the Title Screen press {{Up}}, {{Up}}, {{Down}}, {{Down}}, {{Left}}, {{Right}}, {{Left}}, {{Right}}, {{B}}, {{A}}, {{B}}, {{A}}, {{Start}}.

===By Ti===
*All music tracks are replaced with their better versions created in famitracker. Written by Amilgi without usage of extra audio chips and dpcm channel. Some of sound effects changed too. 

==Unused Music==
Sound Test 2E(Scrap Brain Zone): There's no Scrap Brain Zone at all.

Sound Test 31(Continue?): The game doesn't use continues, so this goes unused.

Sound Test 32(Credits): The game doesn't have any credits, so this also goes unused.
