It was intended to be a simple and small device. Initially, the whole had to fit in the old Game Boy, but the Y-shaped screws were the obstacles. Dreamcast memory card is much smaller but sufficient for this purpose.
Main element is Atmega8A on the stand, so it is possible to write something else and use the console for other purposes. Exactly 99,5% of memory is occupied, which is 8140 bytes. The display is a screen from Nokia 3310. A small amount of space in the housing, unfortunately, made it impossible to use the board, so the whole is assembled “on the spider”. Microswitches were mounted on a piece of plastic with holes drilled. Power supply is a CR2032 (3V). The lifetime of the battery is at least 3 hours.
The goal of the game is to lead frogs through a busy street, avoiding race cars, bulldozers and normal cars. The game has four levels, with each the vehicles speed increases, and every four frogs should be leaded into four leaves on the other side of the road. The player has three lives. The winner wins a reward in the form of the beautiful graphic of frog.
Program MicroLCD was used to create the graphics.
