Here is GOSUB, a homebrew game created for the Mattel Intellivision. Also includes SUPER PRO GOSUB, an enhanced version.
A limited run of 300 serial-numbered cartridges of GOSUB have been created that are compatible with both NTSC and PAL systems.
Each game includes a professional-style cardboard box, color manual, and two overlays.
GOSUB was programmed by Chris Read AKA "atari2600land". Super PRO GOSUB was programmed by Gemini North.
Both games are included on one single game cartridge for your enjoyment and were programmed using the IntyBASIC programming language.
Navigate the mazes of the deadly seas
in a quest to find valuable treasures!
Deep Dive in your submarine in search of sunken treasure chests and vast wealth.
But beware of dangers as these treasures are very well hidden in an underwater labyrinth.
Carefully navigate through the perilous mazes, collect the treasures, and stay alive!
You must pilot through the narrow passages with great skill, as a monster octopus
is lurking around the corner, determined to crush your sub in its mighty grip!
This game cartridge also includes Super Pro GOSUB!
It features more enhanced options, order six new zones to explore, and new creatures!
Bonus levels and enhanced graphics!
