I tried playing both versions on No$Gba both didn't work very well (with the gameshark codes).
i highly reccomend playing the games on DeSmuMe.Desmume is now up to date.And is even faster.
it doesn't work......
i tried to load soul silver and it's working.
but when i try to do it with black/white it's show to me a white screen.
(with desmume_dev, he just can't read it, it says that the specified file is not a valid rom).
oh god why........
That's strange.With me it works.Try to extract the rom if it's zipped,then try again.
