Hello, i would like to make a feature request: the ability to write in the 7zip format. at this time i think 7zip is quite mature, and offers tremendous space reduction due to its solid archive feature. Especially sets with one gazillion clones like the tosec ones would benefit greatly from this. as most frontends support 7zip goodmerged sets, and many emulators too, i think this feature becomes quite relevant. Finaly i would like to ask if it is possible to convert a non-merged dat file to a merged one. a member of another forum has been experimenting with scripts in order to do that, and i want to know if that can be a feature in clrmame. thanks for your time, and for making such a usefull tool
