An open source sprite editor to generate sprites for the Commodore C64!

This GPL3 project uses the open source version of the Qt Framework.

If you're downloading the app on macOS and receive a message saying:

"App is damaged and can’t be opened"

Don’t worry — the app is not actually corrupted. This happens because it is not signed with an Apple Developer ID, and macOS adds a quarantine flag when downloading from the internet.

To fix this, follow these steps:

1. Unpack the .zip or .dmg file (e.g. by double-clicking it)
2. Open the Terminal
3. Run the following command to remove the quarantine flag:

xattr -d com.apple.quarantine /path/to/OpenSprite.app
