Comments and Reviews
The interface within games is often defined/coded using .swf and JPEXS works great if you want to modify those files. I've used this for multiple games (i.e. Fallout 4, The Witcher 2, Skyrim) and they never refused to load modified files.
I do recommend turning off the Ribbon Interface to get a cleaner look (and a window that responds to Windows Snap). The setting is located at "Advanced Settings Interface Ribbon interface [X]", see screenshots below for comparison.
Lags. When I try to decompile some swf's = program refuses to do anything. It can be a corrupted .swf or corrupted java interpreter. -1 star - for lags. But it's open source & (almost) cross-platform, so +es. But it is useful tool.
