Working on the library units for Amiga OS 4 (PowerPC) which was resurrected by Charlie last week. It goes slowly forward. I could make it faster and just copy the Amiga files adjust the offsets and interfaces. But if I do I make it right.. so I check every structures and defines. AmigaDos, Intuition and AGraphics are really huge units. But its already working a little bit 😉 at least can open a window and draw some stuff.
