@xLAKITUx Yes, you should check if the magic number you're using for emgba is included in platform.ini
The platform.ini file included in Rhapsodii Shima is not containing a specific entry for emGBA.
During the work on the plugins pack, I've updated platform.ini and it now includes all the missing magic numbers.
For now you can add these lines in the [PLUGINS] section.
#emGBA
45474241=GBA
and use this number in the plugin .ini and source menu .ini files.
I will release the updated platform.ini with the plugins pack.
@fledge68 I have a little issue with the Hidden category and Titles from Database.
When I use Computer games that are residing on multiple disks or sides (e.g. Amiga games) if I use titles from database, all the disks will have the same name. If I want to display only Disk 1 (to launch the game) and hide the others, all the disks will be hidden, including Disk1.
