(ABANDONED)Mega Man X4 Engine in Game Maker 8.1(Update 5)

EDIT: This project was abandoned due to the codebase being extremely user unfriendly and messy. However a demo can be obtained in the description of the video here:    • Mega Man X4 Engine in Game Maker 8.1(...  
A smaller update this time around,and to be honest that's probably how things will go from here on out until I can get my hands on a proper stage rip that I can re-create a stage with. Nevertheless,I thought I had done enough to share the main points of progress lately.
All of this was done a few months ago and I haven't really worked on this engine since,but with the X Legacy Collection coming up in around 2 months,I think work just might start picking up on this project again. If so,a 6th update might very well come around sooner than usual. Not gonna guarantee anything though.
