This one helped me especially. I actually already had the Developer Menu Hack installed accordingly, but I always hated how each time I would reload a file, my completed research tasks wouldn't remain completed, and the game would register me as having to still research them even on a file currently in use when I used this function. Because of two files from the link above that one, though? I was able to finally get a solution to my problem regarding the Dev Menu Hack that's basically going to greatly make that much more accessible friendly.
Also, for anyone else who has the Dev Menu Hack installed? I actually recommend you get a hold of both All Research and All Things from the above link. Then place both of those files into "dlupdate" or whichever folder you'd place this type of file altogether; *don't* place it in the "Hacks" folder that the Dev Menu itself would be installed in, as otherwise the All Unlock and All Research won't be able to be saved to the file so that they'll remain after being reloaded.
