Amiga 4000 AGA issues

For non WHDLoad games get tude, no4060, degrader and embedder.  These tools will allow you to play a lot of games on your A4000!  Note:  you don't need all of these tools, you can just try one at a time and see if you can get the games working.  I have got XTR running on my A4000 before.

Keep in mind most games only run in PAL, try embedder to run them in PAL.  I would say WHDLoad is the way to go for your setup.  It is unrealistic to expect your monster setup to play older games really.
