I was thinking that too. But the structure of the save files are different, I have almost no idea what I'm looking at anymore.
I was able to find a couple of players in the roster file, but I can't seem to find anyone else.
Plus I think you'd have to calculate the checksum for the specific changes you made (I'm not 100% sure about that, but that's the gist of what I've been reading.) So even if those offsets were found, and we could locate the other players' CFIDs, you'd still need someone experienced enough with checksums to either teach you where it is in the file, and how to calculate the new one based on the changes you've made; or they'd need to make a tool.
Still tons of work left, but seeing that they were able to mod skill points, it's good progress (unless you're an online player then....sorry.)
