A walkthrough of the ZX Spectrum game, Spy vs Spy II: The Island Caper. A 1987 game, sequel to Spy vs Spy (https://youtu.be/p6qnyASdelQ). This is on the hardest difficulty level, with maximum computer IQ.
From the recording originally sent by Pavel Plíva 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.
