Despite receiving almost no support from Toaplan, the team at Ocean France wanted the Amiga port of "Snow Bros." to be as close as possible to the arcade original, playing the coin-op machine from start to finish while using it as reference when taking notes about certain elements such as animations, graphic techniques and enemy AI. Work on the conversion was primarily done on Amiga and Atari ST-based systems, while custom software was written to animate sprites and build stages as a jigsaw puzzle using low memory, which allowed an easier coding process to implement every element from the arcade version like hidden bonus secrets. Artists Philippe and Lionel Dessoly, as well as Francis Fournier adapted the arcade artwork for the conversion, using a ST set-up for maps and sprites, while Pierre Loriaux was responsible for sound design.
