Sonic the Hackable is a Sonic 4/Dimps styled Sonic ROM hack of the original Sonic the Hedgehog for the Mega Drive. It features new layouts, new zones, new moves and a remixed soundtrack by LackofTrack and others.
After Dr. Eggman's defeat in Sonic the Hedgehog 4: Episode II, the Death Egg MK II is left without a power source. Sonic, whose escape pod has landed back onto Mirage Island, is left without Tails, who seems to have landed somewhere else. Knowing Dr. Eggman's resilience, Sonic knows that the evil doctor will stop at nothing to find a new power source to breathe new life into his wicked contraption. With this in mind, Sonic storms off towards the Mad Gear, Eggman's power plant that was powerful enough to refurbish Metal Sonic. Eggman's true plans are unknown, but breaking into his base and destoying his only known source of power sounds like a good start to stop whatever it is.
Now, Sonic must travel through Mirage Island one final time to put an end to this saga once for all.

Sonic the Hackable always make me ponder if Sega should have released Sonic 4 on the Gen/MD instead of those newfangled "next-gen" platforms...
Superb job, too bad this is still a demo, because I want more~! (at least Level Select is still there...)
I really love the art and improvements on this so far! Can't to see the full release!
Once I really wanted Sonic 4 on a mega drive, and you fulfilled this little dream. The demo is very colorful and fun, I'm really looking forward to the new version!
P.S. In level select, I saw your developments in future zones, and the question arose why the 3rd act of spring yeard Is music from Forces playing?
probably a placeholder until a proper remix is made
For what it is so far, it's pretty good… Only things I could really comment on, that I think could be rectified in a future update are that Sonic's title screen sprites looks kinda unfinished, on terms of palette choice and overall shading work, not that it doesn't already look nice now… The other being that the main boss theme hasn't been replaced with the unused track from Sonic 3D Blast's 825 prototype yet.
But overall, this hack is still a decent marvel, even in its current state; At least an 8/10.
As a Sonic 4 style sonic 1 hack it's pretty accurate, just with better physics. I guess the only thing would to add the homing attack. Good job so far, it captures Sonic 4 episode 1 pretty well. Just touch ups here and there.
Good level design, good gameplay, good visuals, and the cool little Homing Attack boost thingy was awesome too!
And it basically just made Sonic 4 into an actually good game. So props for that!
Sonic 4 needs more love and this delivers that. Great hack!
very cool but this is a demo and this is so sad but I hope you finish this hack
Wow, this hack has really, really improved since "A Generic Sonic 1 Hack"
As always, great job!
I've always been a fan of Sonic the Hackable. The earlier versions have always had me astonished with the level design's quality. I did not notice major changes since the older versions, but I genuinely think Splash Hill looks splendid here. That's all I can say, though, since not much else has changed since the earlier versions. Can not wait to see the other zones' artistically revamped versions!
