Then two Amiga coders/graphicians, Saviour (Jani Askolin) and Gremlin (both previously X-Men) (sorry, my hazy memory doesn't recall Gremlin's real name right now) joined Pu-239 and produced a couple of nice demos for Amiga, for example one which showed how to create a scroller with copper only. We were watching this demo, and Lovejoy commented that "That's not possible on a C64." Well, that's what he thought, but we proved him wrong. During the same night, the original "Copper" part for C64 was born. By blanking the screen and changing the border color, the demo part (released as the last part of "Amiga Emulation") created a scroller and some music 'equalizer' bars onto the screen.
This inspired us to create more parts 'emulating' Amiga capabilities, and in the end, the parts were combined into the "Amiga Emulation" megademo, released 6.5.1990.
