Not emulated - original hardware and software.
Please note that due to a hardware issue the audio is out of sync by about 10 seconds, this will be corrected in a later updated video.
Also, the aspect ratio for this YouTube video is 16:9 but the CPC monitor has an aspect ratio of 4:3 so you may wish to adjust your
viewing device accordingly.
Malibu Demo 3 is NOT from 1994, but 1989 (https://www.cpc-power.com/index.php?page=detail&num=8208)
Thank you for the correction I will update this post and YT info now.
