blargSNES is far from accurate, and still can't run many games, including those with enhancement chips. I have contributed enough to the project to know what it can and can't do. We can improve it to the point where it could play most games, but accurately? No way. And this is for free. You know how much trouble Nintendo would be in if they made it available on o3DS with problems AND a price?
Can't they? I played some SNES games on my o3ds fine before with blargsnes
