Quote:This project came about as a result of the continuous changes that mamedevs provide the names of the sets out whenever a new version of the executable. The reasons for these changes are manifold: correction of previous errors, addition of new games with similar names, etc.. By the time the project has expanded by collecting not only changes the name of the sets but also a kind of statistical data-base. Currently the file is complete around 60% but I'm working hard to complete it soon.
