Yeah, if you want to use external flash files not compiled by Articulate,
you will need to use a SCORM wrapper like pipwerks. Once you get it working
by itself, you will then need to insert the flash file on a blank slide in
quizmaker. I highly doubt you will be able to have it function hand in hand
with the QM, but it's worth a try. Just make sure in your player.html you
add the script for the Pipwerks SCORM wrapper.
It might come down to either using QM to make your assessments or using your
custom flash to communicate to the LMS database for scoring purposes.
Also, I highly recommend using the Articulate Forums for more info about
this. They are very helpful and can inform you if this is possible or not.
