K i'll just suggest this....the Batillisk 2 included in that software package is not the most recent version. It does not include a Just In Time emulaton method.
Go here: http://www.gibix.net/dokuwiki/en:projects:basilisk2
Get the newest version, throw it in your existing package.
Downlad this http://www.libsdl.org/download-1.2.php
and put it in the Battilisk 2 folder if you havn't already.
Install the newest of this.http://gladewin32.sourceforge.net/modules/...wcat.php?cid=12
Then click Batilisk II GUI, find the rom path under the rom and select it.
Since that 90 meg download came with a disk image, select that as a disk source.
Click start and see if it works.
Once you reach the desktop, Double click Hard Drive, and Look for the Marathon Folder.
Heres an image for yous.
(Ignore Sheepshaver, it is simply a PowerPC version of Batillisk II)
third picutre is A-10 Attack. OS is 8.6 which is why it looks different than 7.5.5
