If you follow Mark R. Jones on Twitter, you may have come across his post about the Diary on the making of MrDo! for the 48k/128k ZX Spectrum.
Mark’s 50 page PDF is a fascinating read for any gamers that want to learn how Mark and co. converted the 1982 Universal arcade game and why it took nearly 2 years (Feb 2017 to June 2019) to complete! Oh yeah, did we mention it is free?!
