Does this skill require specific external tools?

Yes, it leverages the 'uv' package manager for Python dependencies, 'splat64' for ROM splitting, and 'm2c' for assembly-to-C translation.

Can it help fix build mismatches in N64 projects?

Yes, it includes specific logic for resolving BSS segment address issues and calculating correct VRAM offsets without manual assembly editing, ensuring bit-perfect rebuilds.

What is the primary purpose of the n64-decomp skill?

It assists in the structured process of decompiling Nintendo 64 games into matching C source code using industry-standard tools like splat64 and m2c.

How does it handle libultra identification?

It provides a step-by-step workflow to check SDK revisions in ROM headers, find function boundaries, and map symbols from the ultralib source module-by-module.

Game Development

Facilitates Nintendo 64 game reverse engineering by managing project setup, build systems, and libultra identification workflows.

The n64-decomp skill is a comprehensive workflow assistant designed for Nintendo 64 reverse engineering projects. It automates the initial setup using modern tools like splat64 and uv, helps configure build systems with ninja, and provides structured guidance for identifying libultra versions and symbols. By streamlining the conversion of MIPS assembly to C and resolving common BSS mismatch issues, this skill enables developers to focus on accurate decompilation while maintaining build reproducibility and bit-perfect matching.
