Work-in-progress Cyberpunk 2077 New Game+ implementation

A RED4ext plugin native code implementation of parts of WolvenKit's Cyberpunk 2077 save parsing along with providing an ingame API to achieve New Game+. Dependencies include:

• lz4 for save data decompression
• RED4ext.SDK for various types utilized by Cyberpunk 2077, taking advantage of Cyberpunk 2077's runtime type information system and plugin initialization
• RedLib for a simplified way of registering new native classes within Cyberpunk 2077's scripting system
• simdjson for JSON parsing
• ArchiveXL for loading archive files from arbitrary locations

Supports

• Player inventory parsing
• Scriptable system parsing
• Minor implementation of PersistencySystem parsing, being able to parse the player's vehicle garage
• Redscript integration, being able to provide internal game systems the loaded save data

Supported game versions

• 2.12a

Ingame dependencies

• RED4ext 1.24.3+
• Codeware 1.9.0+
• ArchiveXL, version-independent
• TweakXL, version-independent

Save versions tested on

• 2.00+
• 1.63 and older compatibility is not planned due to large differences in save handling
• Savegame parsing may fail when attempting to parse modded saves with now uninstalled mods

To do

• Code cleanup
  • Making everything share a naming convention
