This is a modification to my level builder located here: http://community.clickteam.com/threads/80833-Level-editor-that-uses-MMF2-s-own-frame-editor
I simply overhauled it to use an array instead of the ini object. Other than that it's exactly the same. Array is probably more efficient (and maybe faster) than the ini, is also supported by all runtimes like the ini, and doesn't need any extra encryption added.
Edit: Re-uploaded because I forgot to remove the unused ini object. lol. Also, another thing to note, you could alter it to save/load the file via a selector instead of using the file name string in the paste object's values. Another benefit of the array object over ini. I just left the saving/loading via the string name so you don't have to open the dialog every time you adjust something, not to mention that if you're importing the loading frame into your game, you're not going to want to use the selector anyway.
I just noticed I didn't include apppath$ in the saving/loading portion so I re-uploaded that change. It still saves in the local directory with just the file name but I've been told in the past you should always add apppath$ + the file name so I went ahead and fixed that.
