The lowest-level wrapper for the RSX. It allows developers to construct command buffers directly, offering granular control over vertex buffers, textures, and shaders.

Python-based scripts (or binaries) for creating FSELF and PKG files, which are the containers for PS3 homebrew.

The SDK is not a single program, but an ecosystem of interconnected tools. The 4.75 release includes several critical components: ProDG by SN Systems
