I have been using older versions of MESS with GameEX and it works great, but I tried running the latest version and either they changed the command lines to run the roms or what? I read the manual from their website and it looks like nothing should have changed, but it will not run from command line. From the UI it works great. So I thought I would ask to see if anyone here is using the newer versions of MESS at all? Btw I'm using the 64bit version if that matters at all.
