Choosing a Base ROM: Most hackers start with a popular game like "Pokémon FireRed" or "Pokémon Emerald" due to their extensive documentation and tool support.
Using Hacking Tools: Tools like AdvanceMap (for editing maps), XSE (for scripting), and PGE (for editing Pokémon) are commonly used in the hacking process.
Testing and Debugging: Thorough testing is essential to ensure the game runs smoothly and is free of bugs.
