Oh no! That's exactly the point! They ARE emulating an Amiga while running 3.X apps.
No they're not. They are emulating a 68k CPU, that's it. They're not emulating anything else (like the custom chips, or AmigaOS).
YES! Now you've got it. And have you used Wine lately?
WINE is not an emulator either, actually the acronym stands for "WINE is not an Emulator".
