Run miSim DE in your Browser

(Remember, you can also run miSim DE as an application. See the manual pages, either here or online for more information.)

This is the Open Source version of miSim DE

This version of miSim DE is compatible with the latest release.

However it is missing powerful new features, and may contain some known bugs that you should be aware of. If you find this program useful, or would like access to more Plugins, a wider range of processor support and enhanced development tools - please visit the miSim website to register & download the latest version.

Remember - software can only survive if you support it.

No Java?

Your browser does not support Java, or has Java disabled.

This means youcannot run miSim DE as an applet.

Sorry..


Please note - there is an issue with some versions of Internet Explorer which prevent the Applet from loading settings when this page is loaded from local disk. We are investigating ways to fix this

Quick Start Instructions

  1. Load a HEX file - Click on the 'File' button, then 'Load Binary..' and select the file you wish to load. Note that the online version can be set up to provide a controlled list of files, ideal for classroom demonstrations. In this case, you have the choice of Pong or Tetris.
  2. Start any Plugins you need - Click on the 'Plugins' tab in the main window. The panel will display a list of available plugins. Click on the required plugin to display information about it, then 'Show' to display it. Note that while a plugin is activated, it will slow down the top speed that the emulator can run at, so only activate the ones you really need. If you are trying out the Pong or Tetris demos, you will want to activate the 'TV' plugin.
  3. Click on the 'View' tab to see the program. You can single step the program by clicking 'Step' or 'Over'. To run the program, click run.
  4. In the case of the Pong and Tetris demos, you can now play the games. Player 1's keys are Q,A,E,R,X (up, down, left, right fire) and Player 2's keys are U,J,O,P,M. Click on the black TV screen if keys don't seem to be responding.

Other Things To Try

  • Note that the speed that the simulator runs at, and other information is recorded on the Log tab. Messages are also shown at the bottom of the applet, in the status bar.
  • You can also load assembly files. The demo programs come with their assembly files that you can build and run. Choose File -> Open.. to load a text file for editing, you can try either pong.asm or tetris.asm here. Whilst the appropriate listing is showing, Choose File -> Assemble to assemble the file - and then you can run it as before.
