Finishing implementation of incomplete engines

This project focuses on stabilizing and modernizing five legacy engines in ScummVM: Avalanche, Parallaction, Dungeon Master, Comprehend, and Lilliput, which currently suffer from crashes, architectural issues, and missing core features. The goal is to move these engines from “Experimental” toward a more stable state by addressing key technical problems and improving overall functionality. The deliverable for this project is to significantly improve the stability and reliability of these engines.
