The game takes place inside a bacteria factory. You walk around and spray the various bacteria with yeast. That will turn them into white happy cloud-like bacteria. If you spray them again they will turn malevolent, so make sure not to overdo it! Move all the happy bacteria to the little bottle to clear the stage.
In this simple riff on an arcade classic, released in 1983 for home microcomputers by famed game developer/publisher Ocean Software, guide a small frog across a busy road, then across logs floating in a river, to reach safety on the other side.
Maggotmania is a single screen shooter inspired by the arcade game Centipede where you control a blue creature at the bottom of the screen trying to destroy a large maggot that appears at the top of the screen over various levels. You can move left or right, and forwards a short distance as well as move backwards and you keep firing upwards when you fire your weapon. The maggot moves across the screen and when it hits a flower or the edge of the screen then it moves down one place and moves the opposite way. When you hit the maggot, it splits into two parts and keeps moving downwards towards you leaving behind a flower. Flowers stop your bullets but after a few shots it disappears and if you hit a flower then you lose one of three lives. Other creatures make an appearance like a spider and snail and these can be shot for bonus points. If the maggot reaches the bottom of the screen then it starts to move upwards and when destroyed you move on to the next level.
You are the Cannon Man and you have to shoot the bouncing ball. When you hit the ball it will fall apart in two or three smaller balls and If you hit those smaller balls, they will also fall apart into two or three smaller balls. And if you hit the smallest balls again they will disappear. The gameplay is straightforward, you can only move from left to right and can shoot straight up. Don't get hit by the bouncing balls!.
In Plasmania, you are a microscopic ship traveling through your patient's bloodstream destroying viruses and pathogens. Be careful though! Every time you shoot or run into enemies or the wall of the blood vessel, you make your patient sicker. The game ends when the patient sustains too much damage and dies.
This is a straightforward clone of the arcade game Centipede. A long slithering alien being gradually moves down a gridded playing area and must be shot out before it can reach the bottom, with the ability to move your ship in all 4 compass directions. Curiously, it doesn't seem to be possible to get a joystick to work in this, despite the chance to define keys.
An extra-rare prototype cartridge. Only one is known to exist.
5200 Menu is a rare prototype that seems to be a kiosk of sorts. The game features Asteroids, which was never released for the system, Quagmire, which nothing is known about as it was canceled, and Failsafe, which was the working-title name for Countermeasure.
Mississippi has been hit by a deadly storm, leaving many boaters stranded. You control the more powerful SS Commodore, and must boat through these hazardous waters and rescue as many of these as possible. This involves travelling up a succession of screens, each of which has one person to rescue, while avoiding static rocks and debris. The screen layouts each time are random, so it is not always possible or safe to rescue the boater. You start a screen in the horizontal position you exited the previous one, so a central exit maximises your chances on the next screen. Other boats travel horizontally across the screen - contact with these results in losing a life. A tap of the fire button gives you a quick boost of speed, useful for avoiding hazards.
