I took a closer look at the "savefile.htm" info (it's posted on the SCEA site in the Documentation section) that describes the save file format. I didn't realise before, but it looks like those hundreds of bytes of diffs are really different icons for each save file! I assumed all "FF7" saves used the same icon for each save file, but they got cute and used a picture of a different character for each file. Given this, there are only a few bytes of diffs outside the header in my "save", "play 1 sec", "save" files. I wonder if the image must match with the save game number? Previously I was downloading GAME1 (whatever the name was), editing it, and re-uploading it as GAME2 (didn't want to wipe out the original). Maybe it doesn't like the fact that GAME2 has GAME1's images embeded in it? Maybe one of the changed numbers has to match with the embeded image? It's easily checked. I'll post if I make more progress. > What I wouldn't mind knowing is what the format is for the little animation > each save contains.

Like I mentioned above, check out the SCEA Documentation section for a file called "savefile.(whatever)". It's got the format you're looking for. Ed Federmeyer
