A walkthrough of the 2007 ZX Spectrum game, The Amazing Rocketeer. A nice looking game, shame there's no sound.
There are six levels, each as a separate load, and it loops back to the beginning of the level after it's completed. 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
