Most of my 68K programs are system friendly and work just fine with OS4. However, I have a few very old programs which require AmigaOS 3.1 and will not work with OS4. They will however work with E-UAE (the Ubiquitous Amiga Emulator). Some of the old games expect classic Amiga hardware, which is emulated by E-UAE.
The OS4/PPC version of E-UAE has been available for many years. E-UAE is the same concept as WinUAE and Amiga Forever. It allows a person to emulate a classic Amiga on newer hardware. You require an Amiga Kickstart ROM and Workbench files, which are not included in the E-UAE package.
In my case, I have used E-UAE for several years to create an AmigaOS 3.1 system for a few very old programs which will not run on OS4. When I launch E-UAE, a Workbench 3.1 Workbench Screen opens up ontop of my OS4 Workbench and I am able to run the old programs just as if I was using my old Amiga 2000HD. This method has worked ok for me.
The RunInUAE package included with OS4 Update 4 automates many of the steps I currently do manually. I have not tried this program yet.. I am assuming the Amiga Kickstart ROMs and Workbench files have been included with OS4 Update 4 to make it easier for people to use E-UAE and RunInUAE. Many people still like to run older games.
