Sonic the Hedgehog is a platforming action video game. Developed by Sonic Team in 1991, the blue blur himself would become one of gaming's universal icons, and became the first series to stand as a serious rival to Nintendo's Mario series, flaming the legendary console wars.

A classic 2-D side-scrolling platformer, you control Sonic, a blue-colored hedgehog that runs pretty darn fast across the stages (zones as they are called in the game). Scattered throughout the zones are golden rings that Sonic can collect, which allows him to not only take damage, but allow access to special stages. If completed, the special stage will grant Sonic one of six Chaos Emeralds.

Dr. Ivo Robotnik, an evil genius, realizes the power of the Chaos Emeralds, and wants them for himself. As such, Robotnik traps the innocent woodland creatures of South Island. In response, Sonic attempts to free the creatures and collect the emeralds for himself in order to stop Robotnik's plans.

Hey look something totally original that has never been done before!

So why does this exist?
LuigiXHero wanted to finish one hack before he move on from Sonic hacking and what better then a character pak made up of like three of his old character hacks. Only one he shown off publicly before is Luigi but every character hack been a thing one way or another for a while.

So what does this have exactly?

4 playable characters in Sonic the Hedgehog (1991) for the Sega Mega Drive Genesis Entertainment System. Being fan favorite Sonic characters: Classic Sonic, Modern Sonic, Link? and Luigi? Complete with stuff to make them stand out and with that tweaks and changes to some levels to make use of it, though don't expect too much from that. Also 5 soundtracks to choose from.
