If you find E-UAE inadequate, you can install Winuae on Linux or Mac OS X using WINE (Windows is not an Emulator), see picture below:

Installing WINE
a) First, check to see if WINE is installed, open a Terminal window (see Applications, Accessories menu) and type wine.
b) If its not installed then you may get a message to install it, you can either do it via a GUI or the command line e.g. sudo apt-get wine. To install WINE on Ubuntu see these instructions. If you are using Mac OS X, you can install Wine for Mac or try CrossOver for Mac.
c) Configure WINE. To create a .wine file structure needed to store Windows programs run winecfg. In particular make sure the Drives and Audio sections are configured for Winuae to work correctly.
Installing Winuae
d) Download the Winuae-archive zip file using a Browser such as Firefox.
e) Move or copy the Winaue folder and files to the .wine folders in ~/.wine/drive_c/Program\ Files/
f) Create a rom folder in the Winuae folder and place your kickstart files and rom.key (if using Amiga Forever roms) in that folder.
g) Create a disks folder and place any required ADF files in it.
h) If you already have a Hard disk HDF or Directory folder, copy that across too.
i) I find it easier to create an .iso file or an actual CD with all the files required and mount that to copy files across to unix. You can use Nero Burning Rom or a free program such as MagicISO or ImgBurn.
Running Winuae
i) Change directory (use cd command) to ~/.wine/drive_c/Program\ Files/winuae
j) Type wine winuae.exe to start Winuae.
k) Alternatively, go to Applications, Wine, Browse C:\ Drive and browse to C:\Program files\winaue to start Winuae.exe using the 'Wine Windows Program Launcher' to start Winuae.
l) Configure Winuae as you would in Windows. Paths can be configured using Z: drive if needed. See winecfg 'Drives' tab on what drives are mapped to.
