I have worked this weekend again on "Aros Vision" and managed to install "WHDLoad" in it and it really works. Additionally it needs the directory "kickstarts" from skick346 from aminet in Devs: and original ROMs from original hardware or Amigaforever in Devs:Kickstarts. If unpacking not works please reinstall XPK_usr.
Naming conventions for the original ROMs are here:
Example with "Defender of the crown" running with WHDLoad and original ROMs (Amigaforever) on Aros Vision.
I will upload a slightly updated version in the next two days (of course without original ROMs)
Regarding Amigaforever perhaps there will be some news soon, who knows :-)
