and dont forget to backup all your models ( just for fans... ) sound files
sprites and maps
if they are not the default ones that is and are costumized or dled from esf file hosters like esf-world.com or redsaiyan.org
then after the installation return each one and check which of the 2 is better...
just a lil warning cause it will delete everything you have and replace it most likely, not only adding new things, thats what the patch will do
I lost a lot during the 1.2 installation
luckily its all backed up }B-)))
