I was able to get it to work one time, randomly trying different settings. I used CD32 and 3.1 ROM, and the rest of the settings the same as you. First time, it didn’t work. Then, I deleted, and re-added the hard disk file, and it booted right up to the main AGS menu. I saved a game state at the main menu. Tried a few games, worked perfectly. But then I tried the c64 emulator, and it locked up. I had to force restart it, the after that, every time, it comes to the “ insert workbench disk “ animation screen. The save state also didn’t work, it would just kick back out tot the main a600gs menu. So frustrating that it just happened to work that one time! I’ll try tweaking settings some more and see if anything clicks.
