Would it be possible for someone to look at this title pleae.
It works on my beeb with Datacentre, but only with *DTRAP on.
It works in BeebEm in Master mode.
Can we make it a more "universal" version by stripping out any protection or low level disc stuff, or whatever else is going on!

Works fine in BeebEm in Model B mode with Watford Electronics DFS 1.30, but only if the game is run using *RUN BOOT, rather than SHIFT-BREAK or even CHAIN"LOAD" - not sure why!

It's fairly trivial to retrieve the BASIC files (all 10 of them!) from the huge file PA, but then I think that the game is also retrieving the questions from it too, so if it's the OPENUP action that is disagreeing with things, then this wouldn't help!

There isn't really any low level disc stuff or protection that I can find, they've just used a rather obfuscated method of retrieving the data!
