Doing the unholy

Our organization created several simulations using Adobe Captivate Classic, and I am trying to upload a non SCORMed zip file via the Code block upload feature in Rise. The Frankensteined monster actually worked however the simulation is about the size of a postage stamp rather than the 1280 X 800 size we built it in as seen below. Any ideas on how I can fix this (aside from rebuilding the simulations in Storyline)?
