- Ares is a cycle-accurate N64 emulator that supports remote debugging with GDB.
- Ares can run original ROMs or those built from decompilation projects, ensuring byte-for-byte accuracy.
- Setting up GDB for remote debugging involves creating a reverse tunnel and configuring the architecture to MIPS:4000.
- GDB can connect to Ares and use the ELF file from the decompilation project for debugging.
- Breakpoints can be set on functions by name, allowing for detailed debugging sessions.
- A function in Snowboard Kids 2 loads level-specific overlays, with a global variable indicating the current level index.
- Testing confirmed that the level index changes predictably as different levels are loaded.
- The debugging process is manual but effective for understanding game behavior like level initialization.
- The article mentions interest in visual debugging tools and externally generated debug symbols.
- The Snowboard Kids 2 decompilation project is open for contributors, with updates shared on Bluesky and Discord.
