In some Atari demos they have a main menu where you can select a sub menu to load. We can do the same thing in STOS. This routine below allows you to move a character up and down a scrolling platform which is a kind of hallway with doors. You move your character to the […]

STOS sprites can certainly be a pain sometimes. This article aims to make using them a little easier to understand. The default sprites in STOS are software sprites, meaning that STOS has to do a lot of work with them which makes them slow and flicker a lot. It spends a fair bit of processor […]

As you know, there are only fifteen memory banks that you can use in STOS. Yet some games have more than fifteen pictures or music files overcoming the fifteen-bank limit. This is done by simply sticking all the files into one bank on top of each other. This is called Stacking a Bank. Let’s say […]

Welcome to this tutorial on writing a database program in STOS. A simple database that will store information in the way of names, addresses, and other details. I will call this program “STOS Address Book”. Note there are no prizes for guessing a better name. First, what is a database? Well, it’s a program that […]

A collection of STOS Basic routines I programmed. Taken from Stosser, Power and ST+ diskzines HIGH SCORE TABLE: 10 key off : cls 20 dim NAME$(10) : dim SC(10) 30 for X=1 to 10 : read NAME$(X) : next X 40 for X=1 to 10 : read SC(X) : next X 50 for X=1 to […]

As STOS and Amos are similar languages it was easier to port the STOS code of some of my games to Amos rather than rewrite it. In this article, I will show you how to port your code over to Amos. Converting STOS source code to Amos is easy. Simply save it as an ASCII […]

The STOS compiler is a very useful program to have because it does the following things. It speeds STOS programs up to three times their normal speed. It saves the program as a single PRG file so there’s no need to copy the STOS folder onto the copy disk. Compiled STOS programs are smaller than […]

The missing link doc file talks about different kinds of banks for things such as bobs, joeys, blocks, etc. But how do we make those banks in the first place? The answer is simple. On the missing link disk is a file called MAKE.BAS which allows you to convert sprites to other formats. The missing […]

The Missing Link Map Editor (EDDY) is used to set up the scrolling maps that the commands “world” and “landscape” uses. It works similar to the MAP accessory that comes with STOS only we have a larger area. So, what does this map look like then? Well load one of the example files on the […]
