Somari the Adventurer: Sonic the Hedgehog Vol.2

Unofficial continuation of the project started by Jabu to improve Sonic for NES.


This hack greatly modifies a large part of the game's resources to provide a better experience, adding a new soundtrack, redesigning levels, renewing the graphics, and introducing a series of new elements and mechanics, among many other features.

On the other hand, if you are very curious or want to know more about it, we invite you to consult the change log, where you can keep up to date with our progress.

*** Additional Notes ***
==============================
• The main core of "BizHawk" is incompatible with our hack, attached is an image that illustrates how to solve it by changing core in that emulator.

• We decided to focus only on the main version, so all unrelated content is removed (Hummer Complete, Family Kid, etc. - It will be published separately).

• At the moment there is a small bug in a specific sector in Spring Yard Zone, a GIF is attached to illustrate it better.
