In it's present state the program is useless (at least for me). It won't create a virtual machine because it can't recognize the ROMs. These are the _same_ ROMs that work just fine in Catakig 1.16 (classic), as well as other emulators such as Virtual ][ (native), OSXII, (native) and STM (both iterations, Classic). And, yes I have them located in the ROMs folder (Duh!). So, here's wishing the developers the best in their efforts, but right now it's a wasted download.
