A couple of quick notes for everyone
If you are getting an error 91 do the following to fix it.
- Open GBToolbox
- Expand the GameBaseAMY selection
- Right click on the database file
- Click scan and fix
The version available for download now has been fixed and shouldn't cause this problem.
If you run the datafile through ClrMamePro you will get duplicate name errors. Just click Yes (there's quite a few). It will still work OK. The error will be fixed in the next version.
