Help with Game Launcher +VirtuaNES

[Jim]

Hey Guys,

I have been experiencing problems with Virtuanes for some reason and GL. I   set it up and it
works fine. Then I try again and games wont load says "Unsupported format" or  soemthing..but if
i open the game in Virtuanes it works?? I have tried deleteing the config   files and nes.map
checking all the options and reinstalling virtuanes..but nothing works.. I   use debug in GL and
it runs correctly...   virtuanes.exe c:\nes\roms\rom.nes.

But I am not sure why its doing this..it was working great. When i type the command in dos it works

If you can help that would be great
