    I am a new firered rom hacker and I can't seem to understand which flags are safe to use and which aren't. People say using 0x1200 and above are safe but I don't understand it
     
    Here's a list of all the flags in firered
    https://github.com/pret/pokefirered/blob/master/include/constants/flags.h#L524

    The ones labelled unused are safe, obviously.
    The story flags and hidden item flags are used for those events. If you've removed those original events from your game or plan to, so you don't mind them breaking, you're free to use those too.
    Don't mess with the system flags unless you know what you're doing.
