Re: Tape copy protection Doctor Who and the Mines of Terror

Hello I can add this 300 baud support to PlayUEF when I get the chance But I'm not 100% sure whether you are really asking to support an adjustment to a 300Hz base frequency (chunk 0x0113).... or switching to a 300 baud data encoding at the same 1200Hz base frequency but with 4x the number of wavele...

The only reason to change any caps in the atom is if the video is looking a bit shonky.

It now runs perfectly... not seen any ...
