I have v81 already installed on my computer and would like to install v103 as well, while keeping v81 installed.
If I install the Mame-v103 in a separate directory then will there be any problems executing either v81 or v103 (whichever I want)?
I want to make sure there are no registry, highscores, etc ... stuff which will cause problems if I have two different versions of Mame installed at one time....
