If you just want to look at the resources, I think you will find the SE ROM is virtually identical, except for the power management features. This is another reason Mini vMac will likely never support them. When I asked the developer about the practical application of the additional RAM ceiling (8MB), he suggested a build option to artificially increase RAM in the other 4MB compacts (which are theoretically capable of handling up to 16MB, rather than deal with the power management features which do not help him develop other emulators, nor are they supported within an emulated environment. You can test this with the Mac Classic ROM, by trying to adjust the screen brightness via the emulated software Control Panel, (which aside from the built-in disk image, is almost identical to the SE ROM as well). Unless a compelling reason for running some vintage software that only works on the Portable or PB 100 (of which I can think of none), it is likely going to be a long wait before a functional version of a Portable or PB 100 emulator surfaces.
