Hacking Why won't Unlaunch boot game carts?

[GurenTonic]

I can't seem to boot game carts on my DSi through Unlaunch, every time I try I just get a black screen. I'm running Unlaunch 2.0. I notice it's listed as "newly released, don't know if it's stable" on the official website. Is this a sign of unstability?

I think it has to do with the Games itself:
When it shows NTR-xxxx-xxx on the Game Sticker it should work.
When it shows TWL-xxxx-xxx (DSi Enhaned Games) on the Game Sticker then not.For Example Pokemon Black Version 2.
