Part II: Writing Games in Assembly Language News: Game 3 is under construction, at Game 3 Rogueima I. For now Part 1 (Robot) is finished, and we are working on finishing Game 2 before working on Rogueima. Introduction At the end of SD-8516 Stellar BASIC we wrote a game called ROBOTS.BAS. This was a fun take on the classic CHASE or 'robots' game from the bsd games collection. Now, for our study of Assembly Language, let's write a similar game: 'robots.asm'. Don't worry if you're not familiar w…

Game 3. Rogueima I * SD-8516 Assembly Language * Part II Writing Games in Assembly Language * This is Part III. Introduction Let's make a new game. This game will be called Rogueima I: Moongate.

You will just have to come up with your own name later. Sorry, it's too late; I called it and I also call no takey-backeys i…

Write your own Adventure Games in BASIC * SD-8516 edition From the Author When I was growing up, somehow, my friend lent me his VIC-20 in exchange for my intellivision to play the new D&D game. I remember playing games like GOLF and PIRATE ADVENTURE. Then when I was 9 an uncle gave me the D&D Red Box for Christmas. Later, I got a C128 and started playing games like Temple of Apshai, Sword of Fargoal, The Wizard, Zork, the Hitchhiker's Guide to the Galaxy, and Trinity. During these formative…

SD=8516 Stellar Basic Stellar BASIC Stellar BASIC started life as a typical microcomputer TinyBASIC and has grown to include several features of a more complete microcomputer BASIC such as DIM, READ/DATA, strings (ex. A$) and string operations. It is implemented in SD-8516 Machine Language, and comes standard in the VC-3 Kernal for the SD-8516.
