OpenRA

I used the Drives app that comes with the OS. I went and mounted the ISO. Went into options to change the mount point to /mnt/openra and the game still doesn't see it.

I mount the ISO images of Tiberium Dawn, and Red Alert and the OpenRA doesn't see the disks. I mount them individually to try and reduce the odds of confusing the AppImage.

Linux AppImage not recognizing the C&C Tiberium Dawn or Red Alert CDs. I've mounted both ISOs yet it doesn't see them. I'm running Pop!_OS.

I'm running OpenRA on Debian using the AppImage on a Chromebook. How do I enable the developer flag? I am unable to change the UI Scale under options. Also, there's no optical drive on a Chromebook, but I have all the data files from an actual install. Where can I copy and paste them?
