What it is

CodeWizardPS3 was the original PS3 PPU PowerPC assembler. It's over a decade old and it's how a lot of us first learned to write and patch Cell code. PS3 PPU Lab does the same job in the browser: write PowerPC, assemble it, and export it in whatever shape your tool wants.

It runs at ppulab.dev, or you can run it yourself.

Features

• Assembler and disassembler for the PS3 PPU (Cell) instruction set, AltiVec included. The encodings are verified against the ProDG SDK.
• Editor with syntax highlighting, find and replace, multi-cursor, and inline error checking.
• Structs, functions, globals, and imports that span multiple files.
• Control-flow and call graphs for any function.
• Output as hex, raw bytes, C# / C arrays, RPCS3 patch.yml, or NetCheat.
• A public HTTP API so you can assemble and disassemble from a script.

Running locally

npm install
npm run dev

Open http://localhost:3000. Run the tests with npm test.

API

The same assembler and disassembler are available over HTTP.

curl -X POST https://ppulab.dev/api/assemble \
  -H "content-type: application/json" \
  -d '{"asm": "li r3, 0x1\nblr"}'

The docs cover the disassemble endpoint and the response shape.
