Do you hate that weather is layered over the GUI? If so, read on.
Weather effects are loaded as objects, so we can change their obj_attr2 values, which determine how they're layered in regards to the backgrounds. For FE8, the bytes you'll need to edit are:
0x030366 change 80 to 80/A0/C0/E0 light snow
0x03066D change 10 to 10/14/18/1C heavy snow
0x59D960 change 10 to 10/14/18/1C rain
0x0309B0 change A0 to A0/A4/A8/AC BBQ
0x03053C change 10 to 10/14/18/1C sandstorm
0x030B30 change AC to A0/A4/A8/AC clouds
In all cases, a higher number gives a higher priority. The higher the priority, the more things the graphic ends up behind. Please let me know if you find anything goofy when doing this.
