I just tested this out: in Sonic 1, sometimes Tails will jump extremely high (to the point of going offscreen) or float in the air. https://x.com/harpermarierose/status/1694955764538822810?s=46 https://x.com/charlie95148/status/1694979052912918756?s=46
Here's the entire initial list in text, typos included: General bugs: - In My Data & Ranking, if a Sonic 3 Special Stage has a Knuckles icon on it, you do not get the option to select a character when choosing to replay a Sonic 3 Special Stage Bugs found in Sonic 1: - Occasionally, Amy is unable to grab onto the poles in Labyrinth Zone. This isn't consistent and seems to happen randomly. - When the player rolls into a sideways Spring, it temporarily puts them into the air, changing how speed calculation works and making some secrets harder to access. - In Sonic 1's Special Stages, the speed of Sonic's spinning animation doesn't speed up or slow down like it normally should, instead remaining at a set speed. - The after-images for the Invincibility power up appear on the wrong layer, appearing in front of walls instead of behind them. - While using cheat codes, if Super Sonic hits an Elemental Shield monitor or had one previously as Sonic before turning Super, he loses the ability to Drop Dash. - While using the Drop Dash with the Debug Mode cheat enabled, it will sometimes display the wrong graphic for Sonic. Bugs found in Sonic CD: - The Girder sprite in Collision Chaos Zone Act 3 uses glitched colors and appears black and white, instead of using it's proper colors. - On the title screen, there's supposed to be a fade from black before the title screen graphics fully load. Instead in Origins Plus, there's no fade. - On Sonic CD's title screen, the Little Planet graphic doesn't dynamically adjust to the aspect ratio of Classic Mode, causing most of it to appear off screen. - Many Monitors placed on top of Springs will layer the Spring in front of the Monitor, rather than behind it like in the original 1993 release. Bugs found in Sonic 2: - When the player enters a Special Stage with a Shield, upon their exiting the Special Stage the player will lose their shield. - In Casino Night Zone, when the player is crushed by the big blocks, the blocks instantly vanish. - When the player rolls into a sideways Spring, it temporarily puts them into the air, changing how speed calculation works and making some secrets harder to access. - While using cheat codes, Sonic's Insta-Shield sound effect plays the incorrect sound. - While using cheat codes, if Super Sonic hits an Elemental Shield monitor or had one previously as Sonic before turning Super, he loses the ability to Drop Dash. - While using the Drop Dash with the Debug Mode cheat enabled, it will sometimes display the wrong graphic for Sonic. - Despite being able to turn Super in Sonic 1 and Sonic 3 with all of the Chaos Emeralds, Tails is unable to go Super in Sonic 2. Bugs found in Sonic 3: - On the File Select menu, if you have a complete save file with every Super Emerald in Anniversary Mode, Tails's sprite on the complete save icon will flash like the Super Emeralds do. - Tails's unique path at the beginning of Launch Base Zone Act 1 is inaccessible, as the elevator takes him down Sonic's path, rather than taking him up to his unique path. - Near the end of Launch Base Zone Act 2, a zipline puts you onto the wrong layer, causing a pathway with some monitors to be inaccessible. - Getting a 1-Up or Coin causes the stage music to completely reset. - Using the Lightning Shield double jump right as you touch the water turns the entire water to an opaque white making it impossible to see. - The Angel Island Zone Act 1 miniboss still has incorrect colors until you hit it. - The airship during the chase section in Angel Island Zone Act 2 is missing its fans. - Blue Spheres uses the Sonic 2 spring sound, rather than the one for Sonic 3. - When defeating Knuckles in Hidden Palace Zone as Super, the Super theme plays even though Sonic untransforms. - When Amy uses her Hammer Dash as Super or Hyper, the screen doesn't shake like it does for Super Amy in Sonic 1 and Sonic 2. - The balloons in Carnival Night Zone do not respawn when you walk off screen like they did in the original 1994 release. - Mushroom Hill Zone is missing many of its decorations and set pieces. - Sandopolis Zone is missing a few of its decorations and set pieces. -When rolling in the beginning of Marble Garden Zone Act 1, the player is sent off the slope at the wrong angle, causing them to hit a wall. In the original 1994 release, Sonic was sent at a slightly different angle that allowed him to go under that wall and into a secret monitor with a Lightning Shield. - Competition Mode's results will always display a tie, regardless of the actual results. - In Classic Mode, you're still able to choose Amy in Competition Mode. - This game incorrectly uses Sonic Mania's animal sprites instead of the sprites from Sonic 3. - This game incorrectly uses Sonic Mania's checkpoint star sprites instead of the ones from Sonic 3. -Sonic 3 still does not reward you 50k points for beating a level in under a minute. -Sonic 3 still has Mania's Cool Bonus when beating a level. It's not displayed on the results screen but is still counted for the overall score.
Glad they finally fixed the crash that would happen in S1 when collecting all emeralds as Sonic & Tails. It may have been under a very specific circumstance, but I've replayed S1 as the duo a lot to freshen up the experience, so this removed a large obstacle for me. I found a couple more bugs in the latest patch not discovered by that twitter thread; the 12th special stage still rewards an incorrectly coloured Super Emerald, and the Knuckles fight still softlocks if you fight him in a super form/invincibility state. Those are pretty much the only glitches left I want fixed at this point (The rest of the things I want are technically new features, not bugfixes :P)
Just tested this out myself: if Tails is underwater in Sonic 1 for too long, the game crashes. This makes completing Labyrinth Zone impossible (EDIT: Fortunately, this has been patched) https://x.com/charlie95148/status/1695298300176666897?s=46 EDIT: Apparently, now Origins does NOT acknowledge Super Tails and refers to Hyper Tails as Super Tails: https://x.com/daviehedgehog/status/1695594001712423238?s=46 EDIT: There are unique transparency issues between each of the four games when it comes to Amy’s hammer attacks: https://imgur.com/ghYdFS5 EDIT: In Stardust Speedway, Amy’s extended hammer hitbox does not affect the Hotaru badnik, and Knuckles cannot glide into them to kill them: https://x.com/littleplanetcd/status/1712305623939899619?s=46 EDIT: I noticed that Amy’s hammer jump is inconsistent on what it protects her from. When she hammer jumps onto the Sonic 1 Badnik known as Spikes (whose top half is covered in spikes), she does NOT get hurt. However, Hammer Jumping on a spikey Pointdexter Badnik in Sonic 3 actually WILL hurt her (and it’s when the hammer touches it, not Amy herself)
