I'm a begginer in this subject and I only know how to extract the romfs and exefs folders with braindump+some commands on CMD and editing a rom with Pk3ds and rebuild the romfs. That part is ok, but I couldn't see the options for editing TM/HM, Market and Pickup. Some pages ago I learned how to edit those options by renaming the exefs folder and .code.bin file. I can click Rebuild Romfs and click Rebuild Exefs, but I don't know what to do with these 2 files now. Can anyone help me? If this is not the right place to ask this question, can someone tell me where I can ask for help? Thanks!
