Supaplex is a video game created by Philip Jespersen and Michael Stopp, two Swiss students, and published by Digital Integration in 1991.

Since then the source code has been lost. Some enthusiasts have disassembled the game, fixed many bugs, and added many features. Today the game and the so-called speed fix can be downloaded free from here. The source code for the speed fix is likewise, unavailable.

OpenSupaplex is a 1:1 reimplementation of the original game in C and SDL, with just a few changes to make it easy to use with game controllers, and also easy to port to any platform.

About Supaplex

Supaplex is an extended clone of Boulder Dash, but it introduces a number of new elements that were not present in Boulder Dash, including bugs, pieces of base that randomly cause a life-threatening electrostatic discharges, Ports, which limit Murphy's movement to specific directions, and terminals, which set off yellow Utility Disks.

Utility Disks are explosive floppy disks and come in three different colors: Orange Disks work like Zonks, but explode when hit or when falling. Yellow Disks do not fall yet may be pushed in any direction, but not pulled (which allows creating Sokoban-like puzzles), and explode when the Terminal is used. Red Disks can be carried and dropped when convenient, exploding seconds after.

Supaplex is the first Boulder Dash-like game that is not fully grid-based: while the playing field is an obvious grid, the objects do not "snap" from one grid position to another, but can be halfway or "in between" grid positions while moving or falling. This behavior has led to a number of well-known bugs that can be turned to the player's advantage, many of which need to be exploited to complete fan-made levels. For instance, by turning around quickly, the player can cause an enemy or rock to 'bounce' off Murphy.

The game also applies "gravity" on some levels, which means that Murphy will fall down empty spaces and will be unable to go back up, unless he climbs up by using bases. Gravity is not actually designated - the player can only notice via trial-and-error.

Changelog

v7.2

  • Switched music from OGG to MOD files, which are lighter and require less CPU usage, which means better performance! Thanks @mills32 for this contribution!
  • Improved renderer for PSP, getting 60fps most of the time! Thanks @mills32 for this contribution!
  • Thanks to the new renderer, audio quality in PSP has been also bumped.
  • Switched sound effects from OGG to WAV. They require less CPU usage, which is another increase in performance and simpler packaging!
  • Now there is only one build for both Old and New Nintendo 3DS.
