Commander Keen 1: Marooned on Mars | 1990 | The Kid Who Explored Mars | 4k CRT Simulation
1Shortplay of the game Commander Keen 1 Marooned on Mars, the MS-DOS game by ID Software.
GAME INFO:
Billy 'Commander Keen' Blaze, an eight-year-old genius, has flied to Mars in his Bean-with-Bacon Megarocket build out of common household objects. But while Keen was exploring Mars, the alien Vorticons stole vital parts from his ship and hid them in the Martian cities. Now Keen must find the stolen parts if he wants to return to Earth.
Commander Keen 1: Marooned on Mars is the first in a series of platform games. Your objective is to find the 4 missing parts to your ship. The game begins with a top-down map of Mars. This is the level select screen, where you can walk around and choose the next level you want to enter. On each level, you have to find the exit, and possibly grab a missing rocket part which may be on the level. Once you reach the exit, you're back on the map of Mars.
The technology/programming of scrolling the screen pixel by pixel instead of large blocks was a new thing on PCs and was quite impressive. Designers who participated in the development of this game: John Carmack, John Romero, Adrian Carmack, Tom A. Hall
GAME RECORDING INFO:
The game was emulated at Retroarch, using DOSBOX core. It was integer scaled to 4k, without bi-linear filtering, and retaining the original aspect ratio (display aspect ratio, not internal resolution). And captured using shader / filter that simulates the image of a CRT monitor screen. I also use a bezel above the game, a 3D scenario with a PC, to create a nostalgic atmosphere.
