• Without assets from the official releases this decompilation will not run.

• Video tutorial on how to find your legally obtained Data.rsdk file: https://www.youtube.com/watch?v=gzIfRW91IxE

• You can get the official release of sonic 1 & sonic 2 from:

  • Sonic 1 (iOS, Via the App Store)
  • Sonic 2 (iOS, Via the App Store)
  • Sonic 1 (Android, Via Google Play)
  • Sonic 2 (Android, Via Google Play)
  • Sonic 1 (Android, Via Amazon)
  • Sonic 2 (Android, Via Amazon)

Even if your platform isn't supported by the official releases, buy it for the assets (you don't need to run the official release, you just need the game assets)

If you want to transfer your save from the Android pre-forever versions, you can go to Android/data/com.sega.sonic1 or 2/SGame.bin and copy it to the SData.bin in the EXE folder.

Additional Tweaks

• Added a built in script compiler. Similar to CD, but tweaked up to match the new syntax for the scripts used in RSDKv4.
• There is now a settings.ini file that the game uses to load all settings, similar to Sonic Mania.
• Dev menu can now be accessed from anywhere by pressing the ESC key if enabled in the config.
• The f12 pause, f11 step over & fast forward debug features from Sonic Mania have all be ported and are enabled if dev menu is enabled in the config.
• If devMenu is enabled in the config, pressing f10 will activate a palette overlay that shows the game's 8 internal palettes in real time.
