simpleJ emulates a simplified computer on your PC: a retro-style video game console that lets you understand how a computer works and write your own video game programs. The first microcomputers were quite simple. They had a few kilobytes of memory and couldn't run large programs. Many didn't even have an operating system. Yet they had something valuable: understanding everything about their hardware and software was easy. simpleJ aims to make this possible while running on modern PC hardware.

Paratim (Paratrooper Improved) is a remake of the old DOS game Paratrooper. The player plays with the gun in the bottom center of the game while helicopters fly overhead. Those helicopters sometimes drop paratroopers. When their are four or more paratroopers on one side of the gun, the game is lost. To prevent this, the player has to shoot the paratroopers while they fall or shoot the helicopters. After a round of helicopters, planes arrive that drop bombs aimed at the gun. If a bomb hits the gun, the game is also lost. To prevent this, the player has to shoot the bomb or the airplanes.
