Sonic 2 (2013 - iOS/Android) Post-Release Bugs/Fixes/Suggestions

Not bugs, but I was thinking that these areas could maybe be "fixed". The miscolored grass due to the original limited palette, and Sonic (and other objects) could appear behind the lava but infront of the background wall. Both aren't big deals, but they always bugged me a bit in the original.

 

Im not sure if this is mentioned already but I've noticed the following (mainly on 2p vs)

Dsynch on the special stages
If both plays pass the spinner at the end of the stage while being too close to each other game freezes

A few differences:

While on the Aquatic Ruin Zone act 2

This area I used to be able to jump through the ground to the top on the android version its solid



This spring (the yellow spring in the water, not shown in this screen shot) used to be able to propel my character to the top. But now I have to use the additional red spring next to the boxes to get to the same place. Because that area is solid in the android version.






Other than that its a great game especially with the hidden palace and 2p vs mode online the achievements are a lot of fun.

 

Has anyone besides me experienced an intermittent bug with the opening/closing platforms at the bottom of WFZ on iOS? On 99% of my attempts, the last four or so platforms never come out. The number of missing platforms sometimes changes, but only once have I ever been lucky enough to make it across; every other time there just aren't enough platforms. It's putting quite the damper on time trial mode, although exploring and marveling at the now-finished HPZ has occupied my mind in the meantime.

(Admittedly (and shamefully) I had never beaten Sonic 2 as a kid on my Genesis. Please forgive me if this is the intended behavior and I am missing some trick necessary to complete the level.)

 

I don't believe it's intentional, but it's a problem in both the original version of the game and this new one. The latest patch that's not yet out on iOS fixes it.

 

In 2P mode, if you jump at this one part in CPZ while the other player is in the tubes, you'll get sucked into the tubes:

 

I've come across a 2P logistics issue that isn't necessarily a bug, but does hinder gameplay. In CPZ Act 2, I hit the item boxes under the stair blocks near the beginning of the level (shown in the screen capture) and one made us swap places. I'm guessing since the stairway was offscreen for my opponent, it never lifted on his side when I touched it and remained in the down position, effectively trapping him inside and allowing me to complete the level at my leisure. (He still beat me on the level in points, total rings, and item boxes, though, so I don't feel too bad.)


(h/t SonicZone0 whose map I cut this from)

There were also a smattering of the other 2P issues already mentioned throughout the thread, but all in all it was still fun playing levels in 2P that weren't 2P in the original.

Oh, and since it just happened here, happy new year!

 

I fired up the game for a bit last night on my Nexus 5 and had to deal with a burst of static noise any time I jumped. I played again this morning and didn't hear if the glitch went away or not but I noticed that the Android taskbar (or whatever the thing with the home button on it is called) was overlapping the game, cutting off the life counter.

Also just a minor annoyance, but I'd like it if I could orient the phone in either landscape position when I play. The position it locks to currently means I can't hear the game at all normally because of the poor speaker placement on the Nexus 5. Using an external app to temporarily force the phone's orientation fixes the issue but a hard-coded fix would probably be better for a lot of users.

Thanks!

 

My only gripe lies with the lag on input controls... I can fly through Sonic 2, Sonic 3+K on Mega Drive / Emulator, but on my Tablet, and my Galaxy s3 either touch screen or gamepad, there is a latency on the input. It makes all the difference for me....

 

I don't know if this has been pointed out but all the rings and monitors taken in a level reappear after doing a special stage. This makes for some easy ring collecting to get to the special stages.

Amazing port, by the way. Stunning job on Hidden Palace!

 

I'm pretty sure Sonic 2 on the Genesis did that too

 

Sonic 2 didn't, but it was an explicit change made to S2K to rebalance the game, alongside the easier special stages. Intentional or not in this remake, I much prefer it this way.

 

Interesting! Just had to fire up OpenEmu and have a quick play to make sure I wasn't going crazy but the rings and monitors DO come back after exiting the special stage. Maybe there's a regional difference here? I sure remember playing this when I was younger and enjoying going in and out the special stages in Emerald Hill and trying to collect all the rings, monitors and kill all the badnicks in between!

Andrew.

 

The "change" you're referring to in S2K was keeping the ring amount entering a special stage after completing it. Rings and monitors reappearing in the level is the same for both the original and with Knuckles.

 

You are right. I stand corrected

 

I've got two bugs to report.

In Aquatic Ruin Zone Act 2, if you beat Eggman and jump on the animal capsule and immediately head right, you'll keep going off the screen until you run off it and then it resets the level.

Some images:

Spoiler

The other bug is that if you select Wing Fortress from a completed save file, then clear it, and get onto the Death Egg...your save is no longer is a completed one. It's gets changed to a Death Egg save. You have to complete the Death Egg again until it becomes a completed save again.

 

I was in Oil Ocean 2, fell down near the start because I suck at touch screen controls, tried getting back up via the series of upward blowing fans, didn't have any rings and got shot by one of those seahorse badniks. Sonic died still playing the sideways rotating animation (same one as the corkscrews in EHZ, if it's not clear which animation I mean), the enemy stopped moving and the screen locked, but it never faded and I'm stuck and have to restart the level. In frustration, I started fiddling with the controls, and could actually hear Sonic spinning, but I'm pretty sure I died.

It seems that Sonic's vertical collision size doesn't change even if crouching/spindashing. This casues me to get crushed in areas where I wouldn't be in the original.

Not sure if this was like this in the original, but there's a section in Metropolis 3 where one of the brown pistons launch you so high that you inevitably hit spikes on the ceiling. Also, while the smooth gears look really nice, they make it far more difficult to jump onto at certain points.

The second one is that the top two tiles of Sonic's head are shifted backward by one pixel, leading to his muzzle having a sharp angle on that one frame. It was like this in the original too, and for all I know it could be intended, but it looks like crap and I don't think it was intentional. Viewing the sprite mappings of the Mega Drive version, the top two rows of tiles are aligned to match the tile borders, but the actual art within doesn't match up.

Also, Sonic's sprite for using an air bubble has a bright orange spot on the corner of one of his shoes, this should be dark red instead. This is because STI never bothered to fix the palette clashes on that particular section of the sprite when the palette was changed to accommodate Tails.

 

Oh, we got a fun one to report. It's an oldie but a goodie.

What happens when you're in the transfer pipes in Chemical Plant Zone and the other player just so happens to hit a teleport monitor? Out of level boundary teleport!

I found a place in HPZ where you can get stuck inside a wall by accident:
