Hello,
Maybe it doesn't works because you are not using GB Studio 2?
If it the case, maybe you use the version 1.x, I also have done a patched version of the 1.x (It was not the case when I sent you the previous message).

But if you send me files and the exact version of GB Studio you are using, I will port it with pleasure ;).
