Hope you see this Andy.
Its been awhile, 2016, since I last played #10 Japan Ironman. I want to make sure this newer version is plain Ironman and not the Nasty versions. I'm assuming that Tier 1 is Ironman, T2 is Nasty, T3 is Nasty Nasty?
Also, I've located the files to be deleted in the Scenario file. So to verify, I would need to delete them (.dat files aei10-0x to -0y ie all the existing variants), then put your new files in this folder.
My WITP AE computer skills have severely atrophied, so I want to get this correct. Thanks for your work!
