According to an interview, due to lack of development systems for the Super FX, Linden wrote a set of tools consisting of an assembler, linker, debugger, dubbed the ACCESS, on his own Amiga before beginning development of the port proper. For the hardware kit, he utilized a hacked Star Fox cartridge and a pair of modified Super NES controllers plugged into the console and connected to the Amiga's parallel port. A serial protocol was used to further link the two devices.
According to John Romero, the Super Nintendo port of Doom was developed secretly by Sculptured Software and then brought to id fully complete in order to request permission for it to be published. Romero states that id's response was, "Oh hell yeah!" The involvement of Williams in its publishing would later lead to that company also handling ports to the PlayStation and Nintendo 64.
