    There is a not so known glitch in all 5 versions of Gen IV with the move 258, AKA Hail.
    Basically you can use the move Hail even when Snow Warning has been activated, resetting to 5 turns of Hail in the process.

    To fix this oversight from GameFreak:
    _Open your Gen IV Pokémon ROM with CrystalTile2.
    _Go to the move behavior narc, so either battle/skill/be_seq.narc (DPPt) or a/0/3/0 (HGSS)
    _Go to sub-file 164
    The string for this sub-file should begin with 20 00 00 00 04 00 00 00 07 00 00 00 40 00 00 00, etc.
    Change the 13th byte from 40 to C0.

    What you did here is fixing the trigger for hailing so that the game calls the code correctly.
    Here are the triggers for each of the weathers:
    03 : rain
    0C : sandstorm
    30 : sun
    C0 : hail

    For some reason the 3 other weather-inducing moves were correctly setup, yet Hail wasn't.
    But with this lone nybble change, Snow Warning will now supersede the move Hail no matter what, which is supposed to be the intended behavior.
