Part two: https://youtu.be/HuzVXOzBCwA . A walkthrough of the ZX Spectrum game, Chip's Challenge. This is in two parts, as it's longer than the 12 hour maximum allowed for YouTube. This part shows levels 1-136. From the recording originally sent to http://www.rzxarchive.co.uk/
Recorded using "rollback", a feature of the emulator which allows you to mark a point, which you can then roll back to later if you get into difficulty, and try again. More info. on the channel "About" page: https://www.youtube.com/user/rzxarchive/about
