@csilverman @halcyon @root42 This was the strategy used to get existing apps to work for the public demos of Copland DR0. Bug fixing the OS one broken API call at a time or having Gestalt lie to the app about what was available. “Edition Manager? What’s that?” I’ve forgotten the full list of apps I got working, but I remember specifically doing Photoshop and Marathon, the latter resulting in one of the worst KON & BAL’s Puzzle Pages ever published.
