The most Amigans think that they are dependent from WHDLoad.
That's not true...
I run several games from HD that doesn't have a
HD-installer, or without the use of WHDLoad.
If the game is no NDOS, just copy the disk contents
to a directory on HD. Eventually you can assign the
game.
Then you can use little programs like "RunIt", "Run500",
"SetChipRev" or "Degrader" to run the game.
If your processor is 68040/68060, then turn of cache
and burst with the Cpu command: "c:cpu NOCACHE NOBURST".
This does the trick for me 9 out of 10 times with
old games that doesn't have a (WHDLoad)HD-installer.
:-D
