When I pick a game and press Play, I just get a dark blue screen and after 30 sceond It goes back to the main screen.

When I install MAMECE3 in my PDA, it prompts me if I want to replace the file "windows\gx.dll from 6/7/01" with the 13/7/02 one; after clicking "yes" I then prompts me the file is a hidden, read-only or system file if I really want to proceed and I click yes.

I have re-installed it clicking "no" but still not work. The questions will be asked every time I re-install it (even if I said "yes" in the previous intallation)".

The software is very promising, please help.
