Supaplex

Supaplex is a video game created by Philip Jespersen and Michael Stopp, two Swiss students, and published by Digital Integration in 1991. It is an extended clone of Boulder Dash that was first to employ smooth and asynchronous movement. While most clones of Boulder Dash employ a cave-like underground theme – Supaplex uniquely uses a “computer insides” theme.

Supaplex lore

In lore, Supaplex is the equivalent of the universe, everything that exists is part of it. It also refers to the order and purpose of all existence, making Supaplex essentially the cosmos and the philosophy of why everything in it exists. Denizens of the Supaplex universe assume there is a reason and purpose to everything. There are various ideas about it, but it is still an unsolved mystery. Actions of the denizens of Supaplex are driven by their beliefs about what Supaplex is.

Original Supaplex

It is a term used to refer to Supaplex versions that were officially released in 1991, before any patches and fan-made fixes. It can refer both to Amiga Supaplex and PC Supaplex, but because of massive differences between them it usually refers to the DOS version, because it became the most popular one.

Known releases of the original Supaplex:
- Original release, also called a big box release
- Classic release, also called a small box release or economic release
- CD release

Amiga Supaplex

Supaplex was originally made for Amiga. For reasons unknown the game mechanics were significantly altered when the Amiga source code was translated to PC.

PC code translation is credited to Robin Heydon.

DOS Supaplex | PC Supaplex | IBM Supaplex

Supaplex was initially released for Amiga. Later it was released for IBM-compatible computers, or simply PC. PC code translation was handled by Robin Heydon.

SpeedFix Supaplex | SpeedFix | spfix

SpeedFix is the name of a series of fan-released patches to Supaplex. Herman Perk and Maarten “Elmer” Egmond decompiled the original DOS Supaplex executable and added many improvements, most notably game speed control. On more recent hardware the original Supaplex tended to run at twice the intended speed due to complicated reasons explained in SpeedFix documentation. The main goal of SpeedFix was to make the game run at the correct speed everywhere.

SpeedFix has been decompiled by Cillié Malan. His assembly code is avaliable on Github. https://github.com/cilliemalan/supaplex
