We need some disassembler ace to mod the game's renderer to have a 1x1 mode.
I presume the game renders to a (guessed from the screenshots) 128x100 chunky bitmap, and then there is a C2P module to copy and expand that onto the screen.
I remember playing the demo of this game, in some ways on a fuzzy monitor the chunkyness of the rendering added to the atmosphere, it didn't feel too crisp and angular.
