Let's wait for the title screen sprite sheet.

@Doc von Schmeltwick: Actually, Spinball was referenced by how Sonic animates at the start of Chemical Plant Zone when he shakes himself off, just as he did in Toxic Caves in Spinball.

It's nice to see the references to the underappreciated and otherwise obscure Sonic games:

Sonic the Hedgehog 2 8-bit
SEGASonic the Hedgehog
Dr. Robotnik's Mean Bean Machine
Sonic Chaos
Sonic Triple Trouble
Knuckles' Chaotix
Sonic the Fighters
Sonic R
Even the Sonic OVA and Alex Kidd

and possibly the last level of Sonic the Hedgehog 1 8-bit

....but not Sonic Drift (preferably 2, i..e the good one), either Tails game, Labyrinth, Spinball...ah whatever, it still warms my heart. But how will they outdo this for the future? I'm not sure they can....time to bring back Phantasy Star Classic, Ristar, Ecco the Dolphin, Sword of Vermillion, or Shinobi?

Have the level title words and ending scenes been ripped yet?

@Deathbringer: Most of the enemy names are currently guesswork (and will be updated to the correct ones later), but a lot are from the game's animation file names.
A full list of 'em all is here, or alternatively McAleeCh's post on Sonic Retro.

@Deathbringer
Read the descrpitions for Dolphman's enemy sheets for Sonic CD and Knuckles' Chaotix. If there's no English name, he tends to make one up. Or if there's an English name he doesn't like, ie the Sonic Adventure customs, he replaces it with his own version. When someone other than me finally looked at a KC instruction booklet, he replaced most of the ones on the KC sheet.....but I think Needlenose is still misidentified on both. Not sure though. And there's a chance these are official, through file names or something.

Where are some of these names coming from?

@Mario Playthroughs; Well someone's going to have to put the puzzle pieces in order one day, and this is all the materials we're going to get.

@15KnucklesLover Yeah, But those are impossible to put together.

@LooneyTunerIan Why wouldn't they be?

@LooneyTunerIan; The backgrounds have indeed been ripped, as shown in this image: https://imgur.com/aUG2zfm (Ps. these weren't ripped by me).

That is, of course, if the backgrounds could be all ripped.

Which I highly doubt they'll be.

this game is gunna be fully ripped in like a week

Ho-lee Shit.

Damn, they really went to town overnight.

Holy Shit! Sonic Mania Rips Already!?

RainbowQuestionMark i am working on the title right now

Wish I could play this, but I don't have any of the platforms it's on....
....have they removed the EVIL DRM bullshite from the PC version yet? I have shitey bandwidth.

I wonder if it's going to be possible to rip the backgrounds from this game?
