tried the one on the wiki and it never got past the loading screen when ran through flash player and using file2hd on borne's site does not work. any one having a working download?

It's not a .swf file but here is a working version: http://www.arcadeprehacks.com/game/15105/Mirrors-Edge-2D.html
The hack only effects baddie rush so it has no effect on speedrunning the game.

I could never get it to work using a .swf when I tried as well
