I have found it to behave even better with Win 7. A quick question for ya, what flavor of Win 7 are you running? I am running on Win 7 Pro 64-bit. You may find that there are 64-bit versions of emus that will run better, even though Win7 does a fine job of supporting 32-bit programs.r example, I use the GUI version of Mame (previously known as Mame32 but now under MameUI with both 32-bit and 62-bit versions). I haven't tried to shell it as this is my desktop I use for other things. I have an older Gateway system that I will likely make into my Mame cab PC once the children move out once again. I was going to use my Toshiba laptop as my Mame machine as kind of a portable console, but decided otherwise.
