It was weird I will admit that. My setup: Amiga 1200 with OS3.2.3 a 030 CPU and 64MB of fastram.
The HDD glitched out after trying to load the forst CEO. The other versions just blinked and did not start. I tried many others games including my own SE game just to make sure it was not a hardware failure. But no worries i can try it on my Amiga mini or my CD32. 😊😊
