A port of the second game of Sonic (Sonic The Hedgehog 2) based on a full decompilation of the original game.
This porting has been made by Xeeynamo upon the source code of Rubberduckycooly, who already fully disassembled Sonic CD prior. This could not be possible without his efforts to bring the Sonic games from Christian Whitehead on PC.
Installation
This requires the assets from the official releases of sonic 2:
Download the APK from the Play Store of Sonic the Hedgehog 2, rename the extension from APK to ZIP.
Extract the content, go to the folder asset where you will find a file called Data.rsdk.xmf, that you have to rename to Data.rsdk (video tutorial).
With VitaShell, place the file in ux0:data/Sonic2.
User guide
You will be now able to change resolution between three different options:
- 320x240 for the original Genesis experience.
- 426x240 to enjoy the game as intended on the mobile versions.
- 480x240 to stretch the horizontal resolution to fill the entire PS Vita screen and 480x272 to use every single pixel of that gorgeous OLED screen.
For the fan of pixels this version introduced three scaling modes: Stretched, Fit and Centered. So now the choice if you want the black borders or not is entirely yours.

Known issues
- Sometimes you will notice glitches at the bottom of the screen (eg. title screen). This is perfectly normal as the game is rendering at 480x272 rather than 416x240. It was the only way to achieve pixel perfect resolution.
- Special stages are SLOW. You might want to overclock your PS Vita just for them.
- Occasional slowdowns when the music changes or when some sound effects are played.
