I think I see. I load the scripts, read each one, and to see if its actually yours, I could check for global variables. However theres the problem with Hidden classes. I can get most of them in the manual but then theres Sprite, Bitmap, Window, Tilemap, etc.
Thats when things failed when I tried making my save editor. =\
I guess I could always try and find remakes or something just as place holders.
