Mr. Nutz: Hoppin' Mad

Developer: NEON Software
Publisher: Ocean
Platform: Amiga
Released in EU: 1994

SourceIcon.png This game has uncompiled source code.

Mr Nutz: Hoppin' Mad was an Amiga spinoff of the 1993 SNES platformer Mr Nutz. The Amiga version also had an unreleased Genesis port.

Uncompiled Source Code

Genesis Port Code

The following fragment of unused source code appears on Disk 2. It appears to be code from the unreleased Genesis port, which would confirm that this port was already in development when the Amiga version was released. This particular code appears to be represented in the 2009 source code leak in the file Zoom.asm, which shows a different and likely later version, dated 29 December 1993. The filenames beginning Work: here show that the game was developed on an Amiga with a hard disk drive; in fact, the 2009 leak includes a configuration file for the HiSoft Devpac assembler for Amiga, configured for at least an 640x512 interlaced monitor. By 1993, even most commercial Amiga games were no longer developed on an Amiga, and it was common for Amiga and Genesis games to use a cross-compiler system for MS-DOS like SNASM.

Amiga Build Script

A leftover script fragment appears several times on Disk 2. This script appears to compile Disk 1 of the Amiga version to the third floppy disk drive. Many commercial Amiga games used non-standard floppy disk formats as an anti-piracy measure.
