Well, of course I've read this, but IMO it's not clearly described.
Only the German Analyst-C manual says, that with level a-d the original Leonardo program is used, but none of the English manuals (Analyst/Maestro) states this - they say:
"The installation of the Analyst/Maestro module does not prevent you from playing any of the levels in Leonardo's original program. It does however offer you additional levels."

For me levels of the Leonardo program does not really imply that it's actually also using the Leonardo program!?

But now I remember, that my Analyst and Maestro engines also started with level a3, and I've added this 'Save Reset State' option some time ago especially for this reason, which automatically loads the saved settings (e.g. level e1) for these modules, so that they are really activated - I just forgot to do the same thing for the new Sparcs (will have to save new reset states ...)
