I have even gone so far as to create a cassette image of White Cliffs of Dover, load that with the disk drive emulation switched off, use PCLEAR1 and still there is not enough free memory. Only by putting the Dragon in Dragon 64 mode (which is the reason for using EXEC) is there enough memory for the game.
That was until I rediscovered 'PCLEAR0', as shown in the "Dragon Notebook" http://archive.worldofdragon.org/index. ... n_Notebook, about five minutes ago. Now I can get the tape I created to work in Dragon 32 mode, but the disk version still causes problems - when I try the instructions for 'disk pclear0' RUN stops working, which isn't very helpful.

I don't think I have ever played White Cliffs of Dover, but I have definitively played Wings of War and some other Salamander adventures. As far as I recall, these games didn't use a special loader. I have checked the manual for Franklin's Tomb, and that one is loaded and started by a simple CLOAD and RUN sequence. I don't have the original cassettes handy (stowed away in a box far, far away at my parents' place) but having a look at the source code for all of the Salamander adventures that I have reveal both PCLEAR and CLEAR statements, which indicates that no "special" tricks were played to make these games run on a D32. Again, I'm not sure if White Cliffs of Dover where different.
