Desolve.decomp

Desolve.decomp is a customized and improved saveinstance project inspired by Universal Syn Save Instance (USSI) and similar tools. The goal of Desolve.decomp is to provide a high-performance, flexible, and user-friendly way to save instances without modifying anything in the target game, reducing detection vectors and enhancing compatibility with various executors.

---

Key Features

• Safe Mode: A detection-free mode to bypass any restrictions and save ANY game.
• Custom Decompiler: Added support for executors without native decompilers.
• Performance Optimizations: Utilizes Lua’s latest performance enhancements for faster operations.
• Extensive Executor Compatibility: Designed to work with as many executors as possible.
• Support for Both XML and Binary Formats: Save instances in RBXMX (XML) or RBXM (binary) formats.
• Flexible Options: Configurable options for decompilation, instance isolation, and more.
• Error Handling: Includes fixes for common errors encountered during saveinstance operations.

Installation

1. Copy the script below into your executor:

   local Params = {
     RepoURL = "https://raw.githubusercontent.com/azazelassembly/desolve/main/",
     SSI = "saveinstance",
   }
   local desolve_decomp = loadstring(game:HttpGet(Params.RepoURL .. Params.SSI .. ".luau", true), Params.SSI)()
   local Options = {} -- Customize options here
   desolve_decomp(Options)

2. For detailed configuration options, refer to the Documentation.

Usage Tips

• Binary Format: Use the Binary option to save instances in RBXM format for reduced file sizes.
• Error Recovery: Restart saveinstance from the point of a crash using skip options.
• Safe Mode: Enable SafeMode for the safest saving experience.
• Performance Tuning: Benchmark the script in your executor to find optimal settings.

Completed Features

• Support for XML format (RBXMX).
• Custom decompiler for unsupported executors.
• Error handling and fallbacks for missing executor functionality.
