Hello OP,
Love your work. I noticed one issue that I thought you should be aware of.
It seems your nswdb database integration is not pulling in any of the games with multiple revision releases.
Here are some of the culprits:
The Legend of Zelda: Breath of the Wild
The Legend of Zelda: Breath of the Wild (rev001)
The Legend of Zelda: Breath of the Wild (rev002)
Snipperclips Plus: Cut it out, together!
Snipperclips Plus: Cut it out, together! (rev001)
What is happening is, no matter which revision one currently has in their collection, your software will always assume they have the original (and never any of the rev versions).
I have tested this on your latest version (v1.0.3 as of this writing) and can confirm the software should have shown the revision versions but instead show the original.
If you can please fix this in an upcoming release, it would be appreciated.
Thank you!
