Currently we have 2 Amiga emulators for the Pi: UAE4All and UAE4Armiga4Pi than I've spoken. Both are based on uae4all1, which has no support for HD files.
uae4all2 comes with several interesting improvements, including support for HDF files, AGA...
There remains much work to run the emulator decently as says the user is developing the port, but if it's running on various platforms such as Pandora or GP32X or other with a capacity similar to the Raspberry Pi processing, I can say with total security that this emu goes to the right direction.
I think it is not difficult to compile. As it has done will upload the binary and see if it works as well as on other consoles and devices.
I leave you with a video of the emulator running on a Nexus 10.
