TROUBLESHOOTING

Sonic 3D in 2D has a few options that can be controlled by creating a windows shortcut and adding a command n the destination field of the shortcut's properties. Click on them to know more.

All commands listed below can be entered in the same shortcut, separated by space (EG: /MIS1 /OLDPAUSE).

Machine independant Speed (/MIS1)

Should you face heavy slowdowns in the game, try to run it using the "machine independant speed" option by following these steps:

1 - Make a windows shortcut to the exe of the game
2 - Go into the link properties and add the /MIS1 command in the destination field after the double quotes

it should look something like this:
"C:\BLAH BLAH BLAH\Sonic3D2d 1.xx.exe" /MIS1

3 - hit OK and start the game through that link.


Water effect compatibility (/LIGHTWATER)

As of version 1.08 should you discover that the water in game looks like a large dark wall, try to run the game through a shortcut with the command /LIGHTWATER


Re-Enable Fusion 2.5 OLD Pause System (/OLDPAUSE)

If you experience slowdowns after the new pause system has been released, try running the game through a shortcut using the command /OLDPAUSE this will re-enable Fusion's un-pause system. You will gain some FPS, but you'll be forced to UNPAUSE the game by pressing ENTER.


Re-Enable Genesis Style pause (start only) (/QUICKPAUSE)

If you want to use the classic Mega Drive/Genesis pause with no options, just use the /QUICKPAUSE command within a shortcut.


Re-Enable Breakable Wall Glitch (/SOTALOSESLIVES)

If you feel like you want to forcefully trigger a patched bug discovered by the Speedrunners of the Sonic 3D in 2D tournament, you can do so by enabling this command.

Install instructions

Click On Each Platform for more details:

WINDOWS

Download and unpack the zip file in a directory of choice. The archive includes xinput1_3.dll ("Microsoft Common Controller API") required for the game to work and detect controllers.

If you're downloading a new version, you can open the zip and take the exe into the folder of your previous installation, or extract into the same path and overwrite everything. Both the savegame and control settings will carry over automatically.


LINUX

Special thanks to mindbender444 for a Linux Installer on Lutris:

Sonic 3D in 2D - Lutris Installer

Alternativelly you can follow his step by step guide:

  1. Download Wine version: lutris-5.7-x86_64
  2. set DXVK option off (otherwise would crash immediately after launch).
  3. Use winetricks to install vcrun6. (otherwise the game will crash after input setup)
  4. (optional) Set up a separate wineprefix to keep things clean.

The game works in either fullscreen or windowed mode, but it may crash after switching between full and window a few times during gameplay. Left screen with low resolution after crash. Configure -> System options -> Restore resolution on exit in Lutris settings made the original resolution return the next time it crashed. So, just be careful toggling between the screen modes.


MAC

Special thanks to AnArmyofAnts for the guide below!

First of all, you need to install Homebrew so you can easily install Wineskin Winery.

PART1 - Homebrew

If you have already installed Homebrew (if you don't remember, open the Terminal and type brew -v), skip these steps:

  1. Go to your Applications folder, go to Utilities and open the Terminal.
  2. Paste the code that appears at the Homebrew page and press enter.

PART2 - Wineskin

Now, we're going to install Wineskin. You can also skip these steps if you already installed Wineskin.

  1. After succesfully installing Homebrew, go to the this page, go to "How to Install" and copy the Homebrew code.
  2. Paste the code into the Terminal and press enter.
  3. If succesfull, Wineskin Winery will now appear in your apps.
  4. Next, open Wineskin Winery. If you get a popup saying that it is from an Unidentified Developer, click Cancel, then right click and click Open, instead.

PART3 - Installing 3D in 2D

  1. Open Wineskin and Install the newest engine (in this case, it should work out well with WS11WineCX21.1.0; if you already have this engine, skip this step.) by clicking the + sign next to where it says "New Engine(s) available!".
  2. After the engine installation, click said engine and click "Create New Blank Wrapper". Name the wrapper whatever you want to (would recommend you to name it Sonic 3D in 2D, seems like a good name tbh) and click Ok. Now the installation should begin
  3. When it finishes, it should tell you to "View Wrapper in Finder", click that. Now drag the new wrapper to any place you can remember where it is (the wineskin folder is kinda hard to access).
  4. Right click the wrapper and click "Show Package Contents". Then open the Wineskin app that appears in the folder.
  5. Now download .zip file of Sonic 3d in 2d and open it. At this point you can also download the Saturn DLC, unzip it and extract it in the same folder.
  6. Returning see a menu that says "Install Software", "Set Screen Options" and "Advanced". Click Install Software and go to "Copy a Folder Inside". Then go to where you have the unzipped folder and select it.
  7. You may get a prompt to select where the executable file is, so select "Sonic3D2d 1.xx.exe" where xx is the game's version
  8. Go to Advanced and click Winetricks and search "vcrun6". A part that says dll shows, open that and select both vcrun6 and vcrun6sp6. Then click Run.
  9. After installing the Winetricks, click Close and it should be done. Double click (or right-click Open) the Sonic 3D in 2D.app (which is the wrapper) and it should run fine.

What happens if I haven't installed the Saturn DLC but I've already installed the game!?

Well what you can do is right click the Sonic 3D in 2D.app and click Show Package Contents. Then open the drive_c folder and got to Program Files. Go to the S3D2d-1.xx xx-xx-xx folder (the date and version do not matter), unpack the zip and drag both the "Saturn" and the "Custom" folders into the Data\Soundtrack\ folder without overwriting the existing music. You will be able to set the tracks you prefer in the new "Music Option" menu that becomes available in game.


How to install the Saturn DLC:

Simply unpack the zip, and drag both the "Saturn" and the "Custom" folders into your Data\Soundtrack\ folder without overwriting the existing music. You will be able to set the tracks you prefer in the new "Music Option" menu that becomes available in game.

hm i was wondering if there was a way to download older versions perferably 1.21 so i can try and get my data back or maybe you can send a link for it?

if 3D blast was 2D

I restored the file i downloaded but it still said a virus

(+1)

Thank you so much my problem is fixed!

(+1)

wow ! great

i tried downloading the new version but it didn't work maybe because i'm on windows but idk

Sotaknuck the new version did not work it still said virus detected i think that the virus infects new version of the game tried downloading it but it said virus detected I think that we can only download version 1.33 1.32 or below I just don't think it will work but thank you for trying to fix the problem

I built the new version on a new computer, the game doesn't viruses.

It's the fusion engine being detected as such.

Every single version released so far gave me this issue.

(-2)

virus in the new version 

中国

but cant we just download the old version? 

(-2)

i know its a virus

(-2)

its an virus bro are you serious -_-

ios

you make amazing content

sotaknuck 

Hey I need help! How do I run the game because it keeps saying "cannot load Joystick2.mfx this object might need an external program or library not yet installed" how do I fix that?

From what I know the library Joystick2 requires xinput1_3.dll, which is already included with the game.

I'm currently working on a new patch that will update the libraries 3d2d is using. Once released your problem might be solved.

Ok thank you

ok

Hi, Sotaknuck.
I recently downloaded the last update and i been trying to play it, but i can't go further than the title screen.
I have a very generic joystick that proably is recognized by the program, but no matter wich button i press, nothing happens.
Tried disconnecting it and play with just the keyboard, but, again, no matter wich key i press, nothing happens.

Anybody else having the same experience?

Last version i had, unfortunatelly i delete it, didn't had any problem with the joystick

That's very strange, I'll try to run some tests. The latest Fusion engine upgrade might have created some regressions to take care of...

Will this be on android?

No promises...yet.

it's not on android put it on IOS

pls

When I tried to run it, it said "Windows protected your PC"

(+1)

thats always what it says if you dont get a game from steam or if they didnt pay microsoft for it to not say tha

as far as i know ther will be shadow the headhog

Woah.

With 30 unique detections and an apparent attempt to modify root certificates, this would have to be the biggest false positive I've ever seen. 

So, I did a Traige, and there was nothing suspicious. The events marked in yellow just seem to be a consequence of how this fantastic engine works, and the event VirusTotal noted, where it tries to set a root certificate, never occurred.

I don't know how to manage it. Seems like the last update to fusion made things even worse.

I'm currently working on a new patch, but I don't think anything will be solved, as I'm still bound by the fusion's build function to generate the exe file.

(+1)

With my own game I sent it to microsoft to get it verified(Windows was deleting my own exes as I created them) It cost nothing and took about 24 hours, was super painless. I forget the url though but it was somewhere at microsoft.com I just searched for and followed the links about reporting false positives.

Thank you for the suggestion! I considered doing so, as 1.34 was deleted by windows, but with the newly released 1.35 windows defender seemed to like it on my end, so I guess that updating the extensions must have worked to an extent.

If reports continue with the new version, I'll try to not only send it to microsoft, but to AV companies too.

(+1)

I sent mine to one of the anti virus companies once. I cant remember which one(It was a request from somebody that purchased it)
Again it was simple I just went through the request process, sent the exe and I heard back from them within a day.
It was easy but it would be a pain if I had to do it for every anti virus company.

I'm getting a couple of things saying the file contains a Trojan or malware, which is awfully suspicious

I was getting PUP warnings in windows so I properly scanned the archive after downloading and got positive, high confidence, detections for Trojon.schoolgirl
Please reupload and fix your package. Use a virus scanner on your machine and fix it. If this isn't you doing this delibrate then your packager is comprimised and its injecting this trojan into the exe what you create the app.
This is not a normal 'indie' exe or 'independant' false-positive by the scanner. Upload the exe to virus total to verify.

My kid really wants to play this so I hope you get this sorted!

sonic 3d blast was already 2d.

у меня пишет что там троян(

Not much I can do, as it's an unsigned exe.

Any unsigned exe is easily flagged as a virus just "because", unless its digitally signed or the AVs servers encountered it on enough machines long enough to stop considering it a virus.

(1 edit) (+1)

Gonna be real, this is pretty hardcore misinformation, and dangerous at that. If that were true, you could go on Github, grab just about any repo with recent changes, compile it and expect to get 20+ detections, but that's just not the case.

For what it's worth, Multimedia Fusion is an absolute mess known for this kind of stuff, but generally speaking, that's super bad info.

(+1)

I stated many times through these comments that Fusion is very often flagged as a virus and 3D2D suffers for that though.

You are right with what you say and I admit I didn't word my sentence properly. With "any" I didn't mean "every single unsigned exe", I meant that that a random unsigned exe can be flagged as a virus.

Do you play on doing another Sonic Fangame? it's been a while since you made this game, and it would be nice if you started your own original Sonic fangame.
