Bought it here in itch and could never load up the MAc version to play always an error..... This makes me sad Raydos
Did you try via itch launcher?
If that doesn't work:
show package content on app - contents - macOS - open badmemories executable file.
or to get it to open permanently without the above fix:
Open terminal.
Paste (with a space at the end): xattr -dr com.apple.quarantine
Drag the app onto the terminal, so you get something like xattr -dr com.apple.quarantine /Users/<username>/Games/BadMemories/Bad-Memories.app
Run that command.
The app should now open properly every time without needing to locate and run the internal executable.</username>
