Tips and common pitfalls

• Start with community maps: many ROM addresses and function names are already documented; reuse that work to avoid reinventing labels.
• Use emulators with breakpoints to avoid blind disassembly.
• Be careful with offsets: different ROM revisions shift addresses — always confirm target ROM version.
• Keep good notes: label functions, calling conventions, and data structures as you discover them.
• Share findings responsibly: publish analysis and documentation but avoid sharing ROM binaries.

Capabilities: Support for up to 10 rectangular functions, 6 parametric expressions, and 3 recursively defined sequences. Why Use a ROM for Emulation? The Ghost in the Machine: Decoding the TI-83
