Overview
opcode_count is a Python tool that processes trace logs from the Emulicious Game Boy emulator to profile instruction usage in Game Boy software. It helps developers understand the runtime behavior of their code, which is essential for optimization and performance analysis.
Key Features
- Instruction Frequency Analysis — Counts occurrences of each CPU instruction to identify the most commonly executed operations.
- Emulicious Integration — Works with trace logs generated by the Emulicious debugger's Trace Logger feature.
- Percentage Breakdown — Calculates and displays the percentage of total instructions for each opcode.
- Detailed Output — Generates a sorted list showing instruction mnemonics, usage percentages, and raw occurrence counts.
Philosophy
The tool provides a straightforward, script-based approach to performance profiling, giving Game Boy developers actionable data to optimize their assembly code efficiently.
