JSW Central

This channel features walkthrough videos of Manic Miner and Jet Set Willy games for the Sinclair ZX Spectrum home computer. It complements the content published on JSW Central (https://jswcentral.org).
The videos, created from RZX files (recordings of Spectrum gameplay), showcase games completed as smoothly, elegantly and efficiently as possible—aiming for the best completion time (JSW games) or the highest score (MM games), with no loss of life if it can be avoided (unless stated otherwise, e.g. in the case of speedruns). Walkthroughs depict the protagonist (Willy or another character, depending on the game) progressing decisively, without hesitation, wasting time or unnecessary moves, following the shortest, most efficient route.
The recordings were made using the Rollback technique, which allows a player to mark a position and return to it if needed, enabling retries. As a result, the solutions to MM and JSW games presented on this channel have a tantalising, almost unreal quality.
