I got Doom yesterday and after extensive searching, I wasn't able to find a save editor for it. So, I figured I would move my happy ass into the kitchen and make one myself. I extracted the save using Checkpoint and popped it into a hex editor and started searching for values (health, ammo counts, etc.) and I think I've found some but I haven't been able to compare the values to another save that has the values changed to see if it matches up. While I was searching for the health offset I came across "checksum=1432457201" (see attachment) and not sure where to start figuring out how to rehash the file. Any suggestions?

did you check file size?
the file size is: 140 KB or 143,427 bytes (file size on disk: 144 KB or 147,456 bytes)
the file length according to notepad++ is: 147,427
the file length according to HxD is: 23,042
and the checksum is: 1432457201

I've attached the file but you need to change the extension to *.dat.
