Explore Flicky Island in a 2D side scrolling platformer that takes elements from the other Mega Drive/Genesis games to re-forge an adventure anew.

TROUBLESHOOTING

Machine independant Speed

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 BLAHSonic3D2d 1.23.exe” /MIS1

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

Water effect compatibility

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

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.

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

Install instructions

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.

How to install the Saturn DLC

Simply unpack the zip, and drag both the “Saturn” and the “Custom” folders into your DataSoundtrack folder without overwriting the existing music.

How to play on LINUX

Special thanks to mindbender444 for a Linux Installer on Lutris:

https://lutris.net/games/sonic-3d-in-2d/

Alternativelly you can follow his step by step guide:

* Wine version: lutris-5.7-x86_64
* DXVK option off. (otherwise would crash immediately after launch)
* Use winetricks to install vcrun6. (otherwise crash after input setup)
* (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.
