Ach. I wasn’t aware the original (PE) Ace files had been changed all that much.
Took a quick look and saw the total number of aces had changed but really didn’t give it a second thought assuming the “meat and potatoes” were still intact.

I’ll take a closer look to see what I am giving up. I believe (by memory) to adapt Aris’s mod to a new Aces.txt would be pretty simple - just inserting a line of text indicating there is a “bio” attached to the name. The issue is the sheer number of additions that would have to be made. My head hurts just thinking about trying to keep track of it.
Ultimately the new PE files would have to be a spectacular addition (or game breaking in absence) for me to give up on Aris’s mod.
