The WHDLoad version often starts using NOMMU tooltype, at least this mode works on standard Blizzard 1260.
Thanks for the heads up!
I also discovered that when compiled with latest version of the engine (August 10) the non-WHDLoad *LHA* version doesn't runs through Amiga shell anymore (in the boot-without-startup method to keep highest chip mem).
So, I removed the text recommending that method. But it seems to run through normal Workbench now.
