This is your main directory for Dead Rising 2
datafile.big is the only file we will be replacing, so it would be wise to rename it to datafile - original.big, or whatever you like, just to have a backup plan if we messup.
When you download a mod, it will either be a .zip or a .big
.zip files need to be unpacked. you can use WinZip or WinRar to unpack them.
the datafile.big file is the main file you should find after unpacking a mod file(if packed at all.)
just put the datafile.big file into the directory into the directory(C:Program Files (x86)CapcomDead Rising 2data), overwrite if prompted, and you are done. Enjoy!
