So with the MESS application, will you basically have a dat file for each console system so that if using MAMEwah, you could point to the console system .dat file to use the built-in filters such as no-clones, working roms only, country, etc. Then also, you could display information such as year of manufacture, name of manufacture, etc. as part of the frontend. I have used Goodtools in the past with its "dirs" option to separate all the clones, etc. with some console rom sets. However, I would rather just be able to filter them through the frontend, like MAME, instead of separating them into different folders, etc. by using Goodtools. I was told in the past that MAMEwah cant provide any functions like that without a .dat file like MAME has. Would this app provide those dat files so that filters could be used with MAMEwah? If so--it would truly be a GREAT app and it gets my vote.
Also, IMPORTANTLY, would you have to be using the MESS emulator to make use of the .dat files generated. Could you use the dat files with other emulators?
