Well I have a action replay but when i try to save it to the memory card it says not a valid xbox save. am i doing anything wrong or should i do somthing else

I had the same problem in the zip of the save should be udata/4#####/7##### in that directory structure. I had read a post that said to take out the first numbered directory but it wouldnt work with out it.

what you need to do is make sure you have the 4######### make a new folder called UDATA (all caps) and put the 4####### folder in the udata folder and make sure you delet all the readme.txt files and right click on the udata folder and click add to archive and make sure the archive format is zip and that should do it
