Frogger, an arcade game released in 1981 by Konami. The game was originally released for Coin-Op. In 1983, the game was developed for PCs.
In the game we control the title frog. Your task is to cross the road and the river safely (although more precisely the moat) to the refuge. The flow of traffic along the river (and other animals) depends on the level of difficulty selected. The harder it is, the greater the movement. The task is simple, and the fun of the armpits!
In DosBOX you have to set the number of cycles (SHIFT + CTRL + F11 / F12).
