I can't think of anyone better with emulators so...
I need help get Pokemon Black 2 to work properly on any emulator at all and I've Googled all over the place. Seriously my house is drenched in all my Googles like you don't even wanna know.
If I'm not mistaken, DS emulation still isn't that good yet. Don't quote me on this, however. :V
Isn't there a GameShark code to make it work (on No$gba), like the first game had?
I can't even get it to load on No$GBA. :c
Not sure what to say, but you could still try'em.
