Info from Dave Edwards on 10/11/2025

Here is a brand new library of BBC Master 128 discs from the demo group BitShifters. These demos are all in the Public Domain and scattered around the Internet, so I have brought them altogether with their release dates so that they might more easily be discovered by BBC aficionados.

Note that many of these demos and games are BBC Master 128 only, and use all of its Sideways RAM to do their stuff! These are the most technically impressive demos for a Beeb machine that I've ever experienced so if you've never seen any of them before, you're in for a treat. Make sure to run them in the B2 emulator though - some of them do weird things (or nothing!) if you try them in BeebEm.

Oh, and note that the coder Henley, who is responsible for many of these demos, is the same Henley of The Yorkshire Boys from 1993. :-)

Edit CJR: Used the emulator B1 in M128 mode with OS 3.20 (OS 3.50 failed on one occasion)
