Roll a ball down a track and try not to let it fall off. Jump, accelerate, decelerate, go left or go right. This is a really fun game! Includes seven tracks and a level editor.
Created by a French user, after making a bet with friends that he could design a game in machine language within only 1 hour. The purpose of the game is to get out of the labyrinth and to blow up the other player with bombs. You can catch bombs or bonuses to improve your bomb damages. For 1 or 2 players.
An adaptation of the DopeWars PC game, which is an ameliorated version of Drug Wars. Buy and sell drugs, make cash, and avoid cops; those are the basic rules.
Like the Jezz Ball PC game. The goal is to fill up the screen without hitting the moving balls. Each level gets harder by the increasing percentage of the screen that must be filled up and the increasing amount of balls.
An adaptation of Tron, with a lot of game modes, 2P mode, high scores, and a lot of options. This old version is included because of its lower memory requirement.
This is a library that kills other libraries! Libraries are small attachments of machine code that come with some aplets. You can see if you have any on your machine by pressing SHIFT MEMORY and looking under the Library heading. Most of them automatically delete with their parent aplet but some don't and there's no way to delete them then. This library will do it. Just note the decimal number next to the library in the MEMORY view and then type UNLIB(number) in the HOME view. Providing that it's not in use then it will be gone. You can't delete the UnLib library itself but since it's only 189 bytes in size that hardly matters.
A simple breakout game.
