Yes, I know how to use ordtools. I used the same command prompt and created c255.o. When I go to open it in OEdit-Xbox (v0.2.42) I get "File contains unsupported sections".
Like I said, I was able to use the files that are for Griffey and it worked flawlessly (except for rotating the head). If I was doing something wrong, wouldn't that strike you as odd that the one file you originally used for the sourcing would work, but the others would not?
