[Audio] Disable surf and bike music?

[7feetunder]

Is it possible (using hex edits or some other method) to prevent the surf and bike themes from playing? A Google search turned up no useful results. Note that I'm not looking for a way to do this for a specific area (e.g. later gen Victory Roads), but disable them entirely.

Yup! If you're using decomp, you can stop the surf theme from playing by going to src/field_effect.c, and looking for this method:

u8 FldEff_UseSurf(void)
{
	u16 i, j;
    u8 taskId = CreateTask(sub_80B8D84, 0xff);
	if(gSpecialVar_0x8000 == 113)
		gTasks[taskId].data[15] = gSpecialVar_0x8000;
    Overworld_ClearSavedMusic();
    Overworld_ChangeMusicTo(MUS_NAMINORI);
    return FALSE;
}

All you have to do is delete the "Overworld_ChangeMusicTo(MUS_NAMINORI);" line, and you're good to go. For the bike theme, go into src/bike.c and look for this method:

void GetOnOffBike(u8 transitionFlags)
{
    gUnusedBikeCameraAheadPanback = FALSE;

    if (gPlayerAvatar.flags & (PLAYER_AVATAR_FLAG_MACH_BIKE | PLAYER_AVATAR_FLAG_ACRO_BIKE))
    {
        SetPlayerAvatarTransitionFlags(PLAYER_AVATAR_FLAG_ON_FOOT);
        Overworld_ClearSavedMusic();
        Overworld_PlaySpecialMapMusic();
    }
    else
    {
        SetPlayerAvatarTransitionFlags(transitionFlags);
        Overworld_SetSavedMusic(MUS_CYCLING);
        Overworld_ChangeMusicTo(MUS_CYCLING);
    }
}

Delete the "Overworld_SetSavedMusic(MUS_CYCLING);" and "Overworld_ChangeMusicTo(MUS_CYCLING);" near the bottom there, and you're all set.
