Good points I've to admin.
I didn't do the test, but I think its easy to write down all these aspects, but it's a pain to really test them all.
You have to find the "right" games to test compability.
This test is not _THE_ ultimate C64 emulator test, but I think its a good start for newcomers to C64 emulation.
