Thanks for such a fast response! I'm using Retro Virtual Machine, emulating an Amstrad 664 (I said 6128, but it was my mistake).
After I checked again with an Amstrad 6128, it works fine. The issue was (again) between the screen and the chair :-D
No worries at all! 😄 It happens to the best of us. I’m really glad to hear it’s working fine now on the 6128. Thanks a lot for checking again and for letting me know!
Hope you enjoy the adventure!
