you could use wolgang lorenz' testsuite (the non c64 specific part of it that 
is), which tests all opcodes including the "illegal" ones:

should be easy enough to adapt to other CBM targets at least (although a lot 
of work). if you ever do that, i'd be happy to include the result back in the 
VICE repository so we can run it on other emulators than x64 too :)

trottet, obwohl er den Kriegsdienst verweigern kann - den kann ich nicht 
einmal mehr bedauern. Er hat nur durch einen Irrtum sein Grosshirn bekommen, 
das Rueckenmark haette ihm vollkommen genuegt.
