Re: JavaScript port of Dosbox

New release. The 'I don't have a job' release :) Re-baselined from a more recent jdosbox codebase (although not all the goodies are included/enabled). other bits and pieces: - Better zip file support - New js compiling core (3rd attempt, still a work in progress) - Removed a number of my failed …

Re: JavaScript port of Dosbox

Updated test site jsdosbox.appspot.com Over the last couple of months I have added file upload and tried to increase performance. Press the config icon and select a file to upload into the emulator. Works with small disk images (imgmount) or a regular zip file (mount). Can also upload a standalone …

Re: Java Port

When I first saw the update post, I thought the references to a kernal and WINE meant you had implemented win32 calls something like the minimal sanos [http://www.jbox.dk/sanos/]. I like your approach, very clever indeed. I may have some java gus code to contribute. The output currently sounds a bit …

Re: JavaScript port of Dosbox

Introduced some html5 buzzword compliance. In a nice piece of irony, adding supposedly experimental html5 tech actually improved browser compatibility. I don't have any benchmark figures, but the changes have had a slight performance improvement. Memory usage has dropped considerably. Chrome still …

Re: JavaScript port of Dosbox

Your java code works a treat; it is invariably the code I touched and mangled that causes me grief. Hopefully layering WebGL on top of HTML Canvas will remove the per-pixel access inefficiencies that seems to cause a number of browser compatibility problems.

Re: JavaScript port of Dosbox

Added sound. Only PCSpeaker and basic SoundBlaster at this point. Not able to remove audible ticks from the PCSpeaker emulation. SB emulation fares a little better using Chrome dev channel (with rare lock ups). Have only tested with the default config of sb1, 11025Hz. Anything more seemed ambitious …

Re: JavaScript port of Dosbox

I am not sure what the problem with the iPad safari browser is. I have tried with some success with desktop Safari on a Mac OSX 10.6 machine. Given that it's performance is disappointing on a desktop, I don't think it would run well on a tablet. On the bright side, as browsers evolve they bring with …

Re: JavaScript port of Dosbox

Still making some progress. Planning to clean up and upload the remainder of the JavaScript 'compiler' stuff in the next few days. It took some time to track down a number of 'what was i thinking?' bugs. As to the iPad, adding handlers for touch events is technically easy, but making it fluid and …

Re: JavaScript port of Dosbox

Uploaded new version Added: - Support for compressed disk images (7Zip) - Some internal re-working of runtime exception handling (GWT/JS limitation) - other minor fixes Also added the first stab at a JavaScript 'compiler' to the dynamic core. At this stage it is incomplete and not recommended for …

Re: JavaScript port of Dosbox

The input problems relate to the keyboard handling differences across browsers and operating systems. As to the replaced directory - that contains mocks and stubs. Makes up for things missing in GWT or where the existing functionality doesn't meet my needs.

Re: JavaScript port of Dosbox

Sound is definitely a priority. Did come across a project on GitHub that may assist - https://github.com/bfirsh/dynamicaudio.js Input is also an area in need of work. See http://www.quirksmode.org/js/keys.html for description of the problem. I'm hoping a GWT compatibility layer exists somewhere.

JavaScript port of Dosbox

JavaScript port of jDosbox. Early days - No sound, mouse control. Project: sourceforge.net/projects/jsdosbox Demo: jsdosbox.appspot.com. Chrome only at this stage. Can run Doom, but is not fast enough to be playable at this stage. I hope to make further improvements. It is faster then my previously …
