Yep, it was made using MAMEWAH as FE, when I wrote that little wrapper.
MaLa might send the extra extension, which it shoud NOT to do that. Hince it might have tried to run Sci-Fi Classic.fpt.fpt instead of Sci-Fi Classic.fpt. This because the wrapper It add the extension itself. I should look on that, so it remove the double extension itself.
Im looking into that now.
