It is available on cartridge from RGCD...

... on disk from Protovision...

... and digitally here, as a package that also allows to install and run the game as if it were a native AmigaOS 4 or Windows application (thanks to the VICE emulator).

Requires: PAL C64 computer (disk version: + 1541 drive)
Recommended: joystick
Compatible with: any SID chip (disk version: + 1541 drive emulators, sd2iec devices, fast loaders)


The game sports/utilizes:

  • 100% high resolution graphics
  • sprites overlaying/multiplexing/zooming
  • sprites-background prioritization
  • pixel-perfect collision detection
  • character-based animations
  • parallax
  • raster beam synchronization
  • open vertical borders
  • flicker-free rendering

  • context-sensitive music
  • variable speed music playback
  • code load distribution
  • 50 FPS full screen free positioning (ending only)
  • stand-alone, single-load parts (frontend, intro, manual, game, ending)

To overcome the limitations of the hardware sprites, objects use the following arrangements of sprites (overall size / number of colors / number of sprites - objects):

  • 24x21/1/1 - patrols, Dogguard, satellites, Ghostease, Peekpoker, beams, intro arrow
  • 24x21/4/2 - keys, frontend items
  • 24x21/4/4 - combosses, Super Peekpoker
  • 24x21/5/3 - Brickbot, Lockhead, Cobermann
  • 24x21/6/4 - Zig-Zagger
  • 24x21/7/5 - ending spaceship
  • 48x21/2/3 - ending credits
  • 48x42/1/3 - Ghosthrill, Ghostorment, Ghosterror
  • 72x40/5/7 - antiviruships
  • 48x42/6/13 - guardians

The game programs have been created in a very special way: the source code is written in BASIC-BOSS + 6510 machine language wrapped in a custom C framework -> then compiled into executables for AmigaOS 4 -> which generate highly optimized source code -> which is compiled with the BASIC-BOSS COMPILER into native C64 programs.


MAH is part of a saga that, as of writing, includes six different games.
BOH opens the story, with the Evil Masters bringing chaos to Earth. Huenison focuses on the fight against one of them, the eponymous character. Eventually the Evil Masters were repelled, but, as seen in QUOD INIT EXIT IIm, during their retreat, Huenison and his companions happened to pass by planet Suinio and decided to cause trouble there as well. Having witnessed the Evil Masters' cruelty, the Pemkians decided develop the defense training program that SkillGrid is part of. In MAH, years later, the danger came from the Apocalypser, the weapon that had been developed against the Evil Masters and that the Purifiers activated to destroy the Earth. Finally, KOG assigns a new task to the hero who turned the Apocalypser off.
