Making a Pokemon ROM hack can be a complex process, but here are some general steps you can follow:
Choose a ROM base: A ROM base is an existing Pokemon game ROM that you will use as the foundation for your hack. You can choose any ROM from the Game Boy Advance or Nintendo DS Pokemon games.
Plan your hack: Before making any changes, you need to plan what you want to add or change in your hack. Consider creating a new storyline, adding new Pokemon or characters, changing maps or gym leaders, or creating new items or features.
Use a ROM hacking tool: There are several ROM hacking tools available online, such as Advance Map, Advance Trainer, and XSE Scripting Tool. These tools allow you to edit the ROM's maps, events, scripts, and other aspects of the game.
Create new graphics and music: If you want to add new Pokemon or characters, you will need to create new graphics for them. You can use a tool like Tile Layer Pro to create new graphics. Similarly, if you want to add new music or sound effects, you can use a tool like Sappy to insert them into the ROM.
Test your hack: Once you have made changes to your hack, it's essential to test it thoroughly to ensure it works correctly. You can use a Game Boy Advance emulator, such as VisualBoyAdvance, to playtest your hack.
Share your hack: Once you have completed your hack and tested it, you can share it with the Pokemon ROM hack community. There are several online forums and communities dedicated to Pokemon ROM hacking, such as PokeCommunity and ROM Hacking.net, where you can share your hack and get feedback from other members.
Remember that making a Pokemon ROM hack can take time and effort, but with patience and dedication, you can create a unique and exciting Pokemon game.
