For those interested to get the graphics of any games (even any Lemmings games too) under Amiga by using WinUAE, here's a tool very useful:
GFX Ripper (http://retrospec.sgn.net/game.php?link=gfxrip)
Read the Readme first to know how it works.
I tried getting the graphics of Lemmings 2 and I almost got it! I need more practice to get them and used them in Cheapo! Enjoy! :)
