Full Changelog: 1.3.2...1.3.3

As a reminder, release builds and autobuilds lock the ability to use Origins Plus DLC content. If you'd like to enable it, you will need to manually build the decompilation.

Release v1.3.2

Changelog:

• Added partial support for the Sonic Origins Plus versions of Sonic 1 & 2.
  • Like last time, certain features may not be fully implemented or work properly. It's recommended to run these versions of the games on the RSDKv5U Decompilation instead.
• Fixed later Sega Forever versions of Sonic 1 & 2 breaking when dying with one life left.
• The Coins counter now increments by the given amount when the NOTIFY_ADD_COIN code for NotifyCallback is called.
• Added the colors attribute for Game.xml, allowing for adding custom GameConfig in several different ways.
  • The existing color attribute is still functional and works as it always has.
• Added the ability to overwrite the game/window title via Game.xml.
• Replaced the log prints for going over the script value count with in-game error screens.
• Fixed several bugs.

Starting with this release, release builds and autobuilds will lock the ability to use Amy when playing the Origins Plus versions of Sonic 1 & 2. If you'd like to enable her, you will need to manually build the decompilation.

Release v1.3.1

Changelog:

• Added partial support for the Sonic Origins versions of Sonic 1 & 2.
  • Certain features from these versions have not (and will not) be implemented and issues will occur when running them; see the FAQ for more information. It's recommended to run these versions of the games on the RSDKv5U Decompilation instead.
  • If you're using the decompiled scripts, there's a new gameType flag in settings.ini to toggle between the mobile/standalone code and the Origins code.
• Replaced the old, custom RetroScript v4 compiler/syntax with the official one from RSDKv5U.
  • Because of this change, the old syntax versions of the decompiled scripts and all script mods based off of them will no longer work. Mods will have to be rewritten using the updated scripts in order to function properly again.
  • In addition, mod scripts are now read from Data/Scripts instead of Scripts, similarly to RSDKv3.
• Rewrote the custom 2PVS server to use a Python script instead of a C++ program.
  • It should work a bit better than before, however it's still more or less a proof of concept. Don't expect reliable connections to opponents.
  • Refer to the readme for how to use the server.
• Trying to open the decompilation without any datapack or Data folder present will generate a text file containing a brief usage guide.
• Added more dev tools and overlays.
• Added more features to the mod API.
• Fixed tons of bugs.

How to run on Windows: Take the Data.rsdk file from your legally purchased copy of Sonic 1 (2013) or Sonic 2 (2013) and place it in the same directory as the .exe file.

Release v1.1.1

This release adds proper support for the ability to compile scripts at runtime rather than loading bytecode files.
to run scripts, download the scripts from the script decompilation repo and put the appropriate scripts folder (Sonic 1/Scripts or Sonic 2/Scripts) in the same directory as the exe file and rename the folder called Bytecode/ to anything else.
Note: the game must be running in data folder mode for scripts to work, otherwise bytecode files will be loaded from the datafile

changelog:

• updated the compiler to work with newer syntax scripts
• added an option to disable the start menu (makes saving inaccessible, only use it if you've got a replacement menu)
