I tried the datcenter and it keeps telling me on everything that it is not supported and I need to upgrade romcenter but i am usingnewest version....

Datcenter is not maintained anymore.
You can edit any datafiles with a text editor, or xml editor for the latest.
You can also import old romcenter format in excel (using the corect separator).
