Does the complied dosbox.js support the use of dosbox.conf configurations?

As I couldn't find a way to force specific DOSBox audio and graphic modes without editing the /src/dosbox.cpp defaults and recompiling.

You can put a dosbox.conf file in the root directory of the packaged files to change settings.

Unfortunately placing dosbox.conf file in the root directory of the packaged files has no effect to any settings I apply. Obvious, visual and audio setting changes such as [dosbox] machine=hercules, [mixer] nosound=true, [sblaster] sbtype=none have no effect for me. The default, hard coded settings are always used.

At launch the console generates the following output regardless of the package directory or user account. CONFIG: Generating default configuration. Writing it to /home/web_user/.dosbox/dosbox-0.74.conf CONFIG:Loading primary settings from config file /home/web_user/.dosbox/dosbox-0.74.conf MIDI:Opened device:none

This works for me. I just tried with the 0.74 branch because that's what you're using. I made a conftest directory containing dosbox.conf and Gwbasic.exe. Then I used ./packager.py conftest conftest Gwbasic.exe. The conf file had:

[mixer]
nosound=true

Resulting output was:

DOSBox version d2e4a49 built with Emscripten 1.29.3 3675eb7

CONFIG:Loading primary settings from config file dosbox.conf
MIXER:No Sound Mode Selected.

Okay brilliant it works. I discovered what the problem was.

I was using tab competition so instead of doing ... ./packager.py stryker major_stryker STRYKER.EXE

I was mistakenly including a forward slash when pointing to the executable. ./packager.py stryker major_stryker/STRYKER.EXE

Packager still compiled and created styker.html etc but the dosbox.conf would not be found.

If this is useful, I expanded the instructions to make the steps a bit more clear.

Packaging DOS programs

Web pages for running DOS programs can be created using the src/packager.py Python script. If you have a single DOS executable such as Gwbasic.exe, place it in the same src directory as packager.py and package it using.

./packager.py gwbasic Gwbasic.exe

This creates gwbasic.html and gwbasic.data. Placing those in the same directory as dosbox.js and viewing gwbasic.html will run the program in a web browser.

Some browsers have a same origin policy that prevents access to the required data files while using file:// URLs. To get around this you can use Python's built in Really Simple HTTP Server and point the browser to http://localhost:8000.

python -m SimpleHTTPServer 8000

If you need to package a collection of DOS files. Place all the files in a single directory and package that directory with the executable specified. For example, if Major Stryker's files are in the subdirectory src/major_stryker and it's launched using STRYKER.EXE you would package it using.

./packager.py stryker major_stryker STRYKER.EXE

Again, place the created stryker.html and stryker.data files in the same directory as dosbox.js and view stryker.html to run the game in browser.

You can also include a DOSBox configuration file that will be acknowledged by the emulator to modify any speed, audio or graphic settings. Simply include a dosbox.conf text file in the package directory before you run ./packager.py.

To attempt to run Major Stryker in CGA graphics mode. You would create the configuration file /src/major_stryker/dosbox.conf and include this body of text.

[dosbox]
machine=cga

Then package it using.

./packager.py stryker-cga major_stryker STRYKER.EXE

Thanks for the improved instructions. I just committed them in f29337f with some slight tweaks.
