I believe that these two items are already known. I know that I have already noticed these.
1551 vs 1541: the 1551 is harder to emulate due to three major chips (6502T, 6523, 6525) versus the 1541's two chips (6502, 6526). This is why 1551 IEC mode still exists in YAPE, for those who need the speed but don't need to cycle-emulate the drive.
Anytime you change from one drive type to another (1541 -> 1581 for example), you need to F11 for the change to be fully in effect.... just as if you turned off your 1551 as device 8, and turned on your 1581 as device 8, you should press the white RESET button so that the drive and the computer can see each other.
And yes, you'll lose the .d64 that was previously attached, because changing drive types does not necessarily mean that you also moved the floppy disk from one drive to another.
