This is a great tool to make custom collections. It has some customizations for ao486 courtesy of Flynnsbit:

I'm experimenting with it to see if I can make some handy packs (e.g. Tandy games, Composite games, etc).
Since we can save the "selection" files, those can be shared without any copyright issues.
It packages automatically with TDL which I don't plan using, but it does extract files so another launcher could be used in theory.
