New zero installation distribution of WUDSN IDE

One of the reasons why I created WUDSN IDE is to make it easy for people to (re)start working with 6502 assembly for their beloved Atari, C64 or other machines. As you could already see in the Tutorial part 1 , the installation from scratch is easy and fast.

To make your initial steps even easier, I now provide a ready to run zero installation distribution for Windows 64 bit operating systems. It contains the Eclipse Platform, the latest stable version of WUDSN IDE plugin, all supported compilers and an emulator for each supported platform. All paths to folders, compilers and emulators are pre-configured. Unpack the content of this archive to the directory "C:\jac\wudsn" and click the "WUDSN IDE" link - That's all. Eclipse will open with the predefined workspace that contains "Hello World" examples for different platforms. You can adapt, compile and run the examples with a single click.

The!Cart Studio update released

Actually there have been many updates in the past 2 weeks. You can read the full details on AtariAge . Today I have replaced the standard Java file chooser by an own implementation which uses the native dialogs of the underlying operating system. The main difference on Windows is that now the context menu for files and folder works in the dialog. The main difference on Linux is that the dialog looks like a real file chooser now and not like some crap a teenager did as homework in the afternoon. In addition the display of the banks now adapts better to the available screen size, so the bank blocks are displayed with larger blocks.

Atari Childhood Memories

After a long struggle with hardware, codecs and recording & editing software I finally managed to have a system setup where recording videos is as easy as I always wanted to have it. So I decided to finally start the tutorial series on Programming the Atari XL/XE that I had always planned.

This tutorial series complements the general tutorial series on using WUDSN IDE itself with the knowledge to the Atari XL/XE computer itself. The purpose of the tutorial is to show interested people how easy it is to control text screen, character set, colors graphics screen and sound with just a few lines of code. Starting is very easy.

The tutorial series consists of short (5-10 minutes) videos. In each video I develop and explain the code live to show you the evolution of the source and the immediate result on the Atari. 7 videos of the about 12 planned videos are now available. You can ask questions and post seed feedback via this thread on AtariAge, youtube comments or e-mail. Once I'm though with the basic stuff, I'll create individual videos for the topics you ask for.

The following videos are now available on the youtube playlist:

WUDSN IDE update 1.6.4 released

I've' had a good time at this year's Fujiama Party again and had the possibility to present WUDSN IDE to a lot of people. All of the are now happy "customers" with an environment where they can play around with assembler so easily. When I installed the previous version of the IDE, I found a bug in recent versions of Eclipse which is due to an incompatible change "plugin.xml" file handling. The bug causes the toolbar button to be invisible and locks up the "Customize Perspective" dialog. Therefore I decided to release a new version which contains all the fixes and round offs I have implemented in the past 12 months.


  • Auto completion for ".PROC" now adds "RTS" before ".ENDP" in MADS
  • Auto completion for ".LOCAL" now adds ".ENDL" in MADS
  • Clicking on the link to a non existent file now asks for creating the file. This simplifies creation of includes during refactoring.
    Clicking on a link to a non existent file


  • Error message assignment to include files now normalizes the file separator before comparison, making it more robust in case of compiler bugs (e.g. MADS 1.9.4)



  • Screen shots and descriptions updated to reflect the lasted version


  • How do I compile into ROM images? added
  • How do I compile into disk images? added
  • How to run a makefile script instead of an emulator? updated


  • Section "Further information on assembler programming" added to the installation section of the IDE. The new section contains links to readily formatted source code includes and examples.


  • The toolbar icons now work correctly with newer Eclipse versions
  • Atari 8-bit Graphics 12 Converter works again
  • Graphics editor now properly closes input stream for image files
  • Empty selection and too large numbers no longer lead to exceptions when opening the context menu for "Convert..."
  • Pressing refresh in the graphics converter now always updates the image pane correctly and not only if the size has changed
  • Inline repeats like ":64" in MADS are no longer detected as labels
  • Hex Editor now correctly detects erroneous COM files in case the segment length exceeds the file length (by one)
  • Disk images (for Apple II) are now updated also if only "Compile" instead of "Compile and Run" is used
  • Apple Commander integration is now part of the installation, as it should have been with 1.6.3
  • The HELLO program generated for the auto-start disk images of Apple II now displays a title and uses "BLOAD/CALL" instead of "BRUN" because of this bug in Apple DOS
    10 PRINT "Loading <title>" : PRINT CHR$(4);"BRUN WORLD" : CALL <address>
