Aeon Version 0.58

Filed under: Aeon, New Version — Greg Divis @ 8:20 pm

Hey, I’m still working on this! Who knew? Unfortunately, there’s not much improvement with overall compatibility in this release. I got sick of staring at and debugging disassembled programs, so I started adding things to the user interface and refactoring my code instead. The usual disclaimers apply: this hasn’t been tested much and may not work on your system at all. Use at your own risk.

  • Fixed memory leak when launching more than one program without restarting Aeon in between
  • Minor performance improvements
  • Lots of DOS process management fixes
  • Command interpreter is now less of a kludge and uses interrupt-driven I/O like everything else
  • Added configuration support and configuration editor – not complete yet
  • Can now change drive mountings while emulator is running (with sometimes disastrous results – use only for disk swapping!)
  • Integer divide-by-zero CPU exceptions now handled more efficiently
  • Added command prompt change current drive command
  • Added some primitive MSCDEX support – a _few_ CD-based programs may work now
  • Fixed bug in LMSW instruction
  • Fixed bug in DOS get file attributes function
  • Added support for launching DOS programs/configuration files via command line
  • Fixed intermittent crashing due to bug in mouse driver callback
  • Fixed some issues with how Aeon handles invalid MS-DOS file names
  • Lots of internal code cleanup and refactoring

  1. Thanks for continuing your work. I hope you’ll renew your interest in debugging sometime.

    • Then by all means, use DOSBox. I’ve never claimed Aeon was better.

  3. Don’t stop work over your emulator. I think it’s be better than DOSBox in future, but at now you need to release compability with cga and sound support (and other). “TMNT” and “Clonk” working on Aeon very good, Terminator rampage starts, but not loading. I hope you will continue work on it, and make it faster and better. (Sorry about my English).
