Sonic 1 Character Pak

Hack of Sonic the Hedgehog


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.

Interesting addition

Reviewed By: diablo666 on 26 Dec 2020

New characters - have their own interaction functions: “Modern Sonic - Has all the features from the modern line of games about the Hedgehog”, “Link - Except for beautiful sprites - has functionality from Zelda 2 on the NES”, “Luigi - and all his cunning features of Mario games”. In addition, you can choose “music” from those that are offered to us. And yet - in one of the music playlist - there is a cunning Easter egg for the latest game about the Blue Hedgehog (Sonic Forces), which is an Easter egg. There is training that you can either skip or go through it and learn each character, which is also a plus. The only thing that has not changed: “the Game remains normal, original.” I recommend it because here - you can play for new (really new, and not just “alterations of Sonic sprites”) characters, and they complement the gameplay of the game in their own way.

Version 1.0 Recommended - Yes
