Below are the instructions for compiling the Sonic Robo Blast 2 (SRB2) WASM files and building the launcher website.

• Windows: Git for Windows, CMake, Python 3.x, and a C++ toolchain (Visual Studio).
• Linux: sudo apt install git cmake build-essential python3
• Node.js: Required for the launcher website.

Note: Windows hasn't been tested yet. If it is having issues, try using Github codespaces to compile.

1. Open the Command Prompt (cmd.exe).
2. Navigate to your source directory:

   cd path\to\srb2-source

3. Run the setup and build script:

   setup-build.bat

1. Open your terminal.

2. Navigate to your source directory:

   cd path/to/srb2-source

3. Run the setup script (this handles cloning and builds the engine):

   chmod +x *.sh
   source ./setup-build.sh

4. To rebuild later without running the full setup:

   source ./load-emsdk.sh
   ./build-wasm.sh

This should work on both Windows and Linux.

1. Install Node.js dependencies:

   npm install

2. Build the launcher:

   npm run build

3. Start the dev server:

   npm run start

Note for Developers: If you modify the C source code, you must re-run setup-build.sh (or build-wasm.sh) to recompile the engine. The Node server only watches frontend files.
