mod_battery_icon.py

# the original battery icon looks stupid, with the bars starting on the left and the odd line art. this replaces it with a more familiar design. 
# the two offsets used in fw[0xD348+134:0xD348+223] limit the data to just the battery bitmaps, while fw[0xD348:0xD348] contains the entire set of 8px symbols for future mods
