To do this, we need to change a value that represents the color in a specific memory location. If you take a look at the image above where the emulator is running, you can see that we got a light blue border, and a dark blue “main window” area. Org $1000 We want this program to change the background of the main window. If you convert this to the decimal system, you get 4096. We want to start it at the memory address $1000 (hex decimal). Processor 6502 Next we need to tell the compiler where in the memory the program should start. The C-64 got a 6502 microprocessor, so this is the processor we want to target. The first thing DASM needs is to know what processor we are going to target. There are many different assemblers for compiling C-64 programs (6502 microprocessor), and as they all got their differences I suggest you learn one and stick with it. prg file using DASM, and then run it using 圆4. Commodore 64 word writer 3 download code#We are going to write some code, then compile the code to a. You should now be in a blank test.asm file and be ready to type in some code. Commodore 64 word writer 3 download free#I use Visual Studio 2010 for this, but feel free to use whatever text-editor you want (Notepad, UltraEdit, …).Ĭreate a new source code file names test.asm. Commodore 64 word writer 3 download windows#The first thing you need when writing a program for the C-64 on Windows is a text editor. Now, close the emulator and the cmd screen if you want. A new window will pop up with the classic C-64 screen: The result should be something like below: Now you should be able to run the emulator and assembler from wherever you are on the system. the semicolon is the splitter between different paths: In the popup under System variables (or for the user if you only want it to be available for one user) find the variable Path and add the paths to the exe files behind the other paths. Then on the Advanced tab, click the button: To add them to the environment variables (Microsoft Windows 7), go to control panel, and open System. I usually add the DASM.exe to the environment variables, as well as the emulator 圆4.exe. The assembler, DASM, is very simple to use. Download this now, as this is the emulator we are going to use in this article. The emulator I use is named WinVICE, and you can get it from here. If you are creating a program for a C-64 using an emulator, remember to test the program on a real device as there might be some differences. The emulator will make it possible to run any Commodore 64 program on your PC. Download this now, as this is the assembler we are going to use in this article. The cross assembler I’m using is named DASM, and can be downloaded from here. In my opinion, this makes it a lot easier to create programs as the editors in Windows is a lot easier to use then the editors on the C-64. In this article, I’m going to use a cross assembler and an emulator.Ī cross assembler enables you to assemble the code on your computer, and then later transfer the code to a real C-64 or an emulator to run the program. Note: You do not need to own a Commodore 64 to create programs. If you want more, let me know by writing a comment to this article I might write more articles on C-64 programming if there’s an interest for it. I noticed that a lot of people are creating graphical programs to the Commodore 64 again, so I decided to let you know of the tools I use, and how you can use them to create C-64 apps in Windows. Update: All needed files for this tutorial can be found in the GitHub repo linked in the bottom of this page. ![]()
