I have the freeware version of RA1 with all the expansions, but for some reason OpenRA seems to be unable to detect the mounted Aftermath ISO when it could easily detect the rest. I'm guessing it's because the ISO is named 'CD4' while the other ISOs do have the name of that particular game which they contain.
What do I need to do to get the Aftermath bits installed into OpenRA?
Thank you in advance for your help!
