Damian recalls: "The protection scheme used on most of the titles I wrote was SpeedLock (by Dave Looker- a good friend), apart from The Hunt for Red October, which uses what I like to call 'DamoLock' [;)] Wrote it myself, including the custom tape reading routines. Multiple layers of encryption that were randomly selected at source code compile time, to effectively fill the remaining memory and take a snapshot of the game, whilst encrypting the saver/loader with 'I' reg lookups- pretty simple to code, a total biatch to decode [;)]"
