This might in fact be the final version of DSfix. Why? Because Nwks (the original author of the 60 FPS unlocker!) came back and did something which I had considered ideal for a long time now: make it scan for the addresses it needs to patch instead of hard-coding them.
What does this mean for you as a DSfix user? Hopefully, that when/if the game is updated in the future, DSfix, including the FPS unlocking, will still simply work. The only reason this would fail is if the binary code right around the places which need to be patched were to change, which seems unlikely for the smaller patches which can be expected at this point.
Also, since it seems like some hosts are still taking down DSfix for no discernible reason, here are 3 separate links to it:
Just to reiterate: this version will not work with the GFWL version of the game, only with the beta Steamworks version (which will replace it at some point).
