http://www.cenobyte.nl/pinhead/This latest version has some small bugfixes, but also two new features per request:
1. User can now choose a database location if he/she wants to. This way you can store the Pinhead database on a network location or in a Dropbox folder so you can access it with multiple computers and/or have a backup of your database. Set this in the Configuration screen.
2. The Machine Type pull down ("Pinball", "Arcade", etc.) now can be user defined in the Configuration screen.
