emularity's Issues

how to implement?

it always results in " Failed to download game data!", there is no working example anywhere i could find nor a guide how to implement - for example what should i put in the locateAdditionalFiles function? it would be great to even have a minimal explanation to the different emulators because without a working example in which i could at least inspect the code its unusable to anyone who doesnt understand it already.

VICE.js: Symbolic keyboard

Find a way to default to a symbolic keyboard. Not sure why VICE.js is defaulting to positional keyboard.

Change the DSK in runtime.

Is possible to change the dsk files in runtime? In example for Amstrad/Spectrum/MSX where a lot of games needs to replace the disk from the side A to side B in the same floppy drive to continue.

Awesome work, thanks!!

building instructions for mame emulator

Hello emularity team,

First thank you for this wonderfull loader !
I've tested mamemegadriv.js driver (making some litlle modification to console example html) with a custom rom i've compiled from source and it works perfectly.

Now i'm trying to build mamemegadriv.js from mame source to test some parameters.
Folowing mame docs (in windows 10):

• installed latest emsdk
• put build chain (./bin part) from mame tools in my path
• cloned mamedev repo
• run emmake make SUBTARGET=megadriv REGENIE=1 TOOLS=0 SOURCES=.\src\mame\drivers\megadriv.cpp -j5 in mame directory

I've managed to get mamemagadriv.js and wasm files. But when i try to run the same game with those files i get this error:

exception thrown: 12421456 loader.js:827:45
failed to asynchronously prepare wasm: 12421456
[from chrome dev console ]

My .wasm generated file is bigger than yours ~20 MB, on the other hand .js a file is smaller ~3MB.

Please, can you provide some more detailed instructions to build emulator files from mame source ?

Thanks !

Is it possible to destroy the emulation process in the canvas?

In TECHNICAL.md has methods that allow you to work with the emulator object.

Once you have an emulator object, there are several methods you can call.
start()
requestFullScreen()
mute()
unmute()
toggleMute()
setSplashColors()
others…

I would like to know if there is a method that allows you to stop (destroy) the emulator object? Something like emulator.stop() or emulator.destroi() ...

And by the way. The mute(), unmute(), toggleMute() methods, when using DOSBox, cause the emulator freezes.
This can be observed here: https://archive.org/details/GobliiinsDemo

load custom dosbox.conf

Hi I would like to know how can I load custom dosbox.conf in emdosbox-loader (emularity) (what the difrence between emularity and emdosbox-loader (emularity is better right??)

I was using this code to load file from zip
var emulator = new Emulator(document.querySelector("#canvas"), null, new DosBoxLoader(DosBoxLoader.emulatorJS("emulator/dosbox.js"), DosBoxLoader.nativeResolution(640, 400), DosBoxLoader.mountZip("c", DosBoxLoader.fetchFile("Game File", "emulator/win311-stock.zip")), DosBoxLoader.startExe("windows.bat"))) emulator.start({ waitAfterDownloading: true });
now I also have dosbox.conf in my zip so how can I load it in so emdosbox will recognize it?

Thanks for Anwsering and Best Regards

VICE.js: Add support for vice_drive_8 and vice_drive_9

Might be useful for, say, disks full of utilities, where autoloading anything is the wrong choice.

No sound on Safari in MAME

The Archive.org in-browser emulation of the Game Boy (powered by MAME) doesn't play any sound in macOS 10.14.5/Safari 12.1.1.

To reproduce:

1. Visit https://archive.org/details/demo_is_that_a_demo_in_your_pocket_2015
2. Press Play
3. There's no sound
4. Tapping the Mute button doesn't do anything.

This doesn't happen in Firefox 67.0.4 on the same computer: sound works fine there.

load dos game from folder?

Is it possible to start a game from a folder to work with savegames?

Arcade not work

I can not get the example_arcade to work.
I have the file examples/targ.zip
And I have the emulator emulators/jsmess/mameexidy.js

But it does not work, I leave my code:

 ```

var emulator = new Emulator (document.querySelector ("# canvas"),
null,
new JSMAMELoader (JSMAMELoader.driver ("targ"),
JSMAMELoader.nativeResolution (256, 256),
JSMAMELoader.emulatorJS ("emulators / jsmess / mameexidy.js"),
JSMAMELoader.mountFile ("targ.zip",
JSMAMELoader.fetchFile ("Game File",
"examples / targ.zip"))))
emulator.setScale (2);
emulator.start ({waitAfterDownloading: true});

emularity API Questions

Hi I would like to know how can I use Runtime API found at TEHNICAL.md (what's the difrence between toggleMute() and mute(), unmute()) I would also like to know what does setSplashColors() do? (does it set custom image instead of emularity logo? (if not how can I do that?)

Thanks for Anwsering and Best Regards

keyevent() in Chrome/IE

I found the prevention of the space bar scrolling behaviour doesn't work in Google Chrome or IE.

I updated the function with a solution from Stack and it seems to work http://stackoverflow.com/questions/18522864/disable-scroll-down-when-spacebar-is-pressed-on-firefox

// stashes these event listeners so that we can remove them after
                window.addEventListener('keydown', k = keyevent(resolve));

    function keyevent(resolve) {
      return function(e) {
        if ((e.keycode || e.which) == 32) {
          e.preventDefault();
          resolve();
        }
      };
    };

Cannot run the arcade example: jsmess_set_mastervolume reference error on messexidy.js

Hi, I was trying the emularity Mame example "example_aracade".
I downloaded messexidy.js.gz (the git-annex was not working for this file) and the targ.zip
I also added an undocumented gofullscreen element to the html.
But this error I could not solve. I think that something was added on Mame and was not updated at emularity:

ReferenceError: jsmess_set_mastervolume is not defined
http://localhost/emulators/jsmess/messexidy.js line 407 > eval
Line 1

Thanks for the project, I hope you continue. I´d like to share a few programs developed on an old coco2 to friends :)

add option to disable html title change

so the current behavior is, after zip file loaded, it changes the title to something like DOSBox SVN, CPU speed: 3000 cycles, Frameskip 0, Program: xxx.

I'm currently working on a project that runs in an electron app, so just wondering if it possible to add an option to disable this behavior to make the titlebar cleaner?

Thanks and really appreciate your amazing work!

Other emulations

Hi.
There are emulators in MAME that are not in here, e.g. 'bbcb' (The BBC Micro). Is this a simple job to request this to be added? Might also be worth considering using JSBeeb https://github.com/mattgodbolt/jsbeeb directly. I have a lot of items I'd like to upload to the Internet Archive which would greatly benefit from having an emulator available.
Thx.

Use BrowserFS's New FS Constructor

Hey @db48x!

I just added the ability to construct additional FS modules and use them in the EmscriptenFS in v0.5.3.

Secondary FS modules function identically to the standard FS module, except that you can't do the following:

var secondaryFs = new BrowserFS.BFSRequire('fs').FS();
var writeFile = secondaryFs.writeFile;
writeFile(...) // will fail because secondaryFs is an object with state; writeFile needs to be invoked on it

To use a secondary FS module with the Emscripten FS, simply pass it in as the last argument to the EmscriptenFS constructor.

I hope this helps your modularity story! :)

Let me know if you have any issues or questions.

Better error messages when we fail to decompress a zip file

Please help. I have pulled the repo, did a git annex on the files requested in the example_dosbox.html file, uncompressed the gz files and cannot get the page to load. As a side note, one cannot downlod the files directly. Internet Archive says it doesn't know how to handle them.

Would be cool to use that instead of MESS

Would Like to Help

To preface I am a very very junior 8 weeks into a web dev intensive through GA but want to do a project similar to this for purely selfish reasons, I want to be able to play original game boy games on any device specifically mobile.
I know that I am just starting but am willing to do anything to help.
Even if it is something that you would consider scut work the keystrokes and learning are more important to me than anything else.
Thanks,
Mike

Bring all the mame drivers to the same version

This is a 'nice to have', but since MAME requires save states to be created on the same version of the emulator that they are loaded on, it's a bit of a pain that emularity's drivers are different versions - it means I need to make ZX Spectrum saves in 0.177, and Atari saves in 0.187, and so on. It would be cool if they were all on the same version.

How to run other MAME game?

cpc6128.json has a wrong native_resolution values

i don't know if its the right place, sorry in advance.

The native_resolution in cpc6128.json is wrong -at least the height-
https://git.archive.org/db48x/emularity_engine_v1/blob/master/cpc6128.json
The measures have more sense here (check both native_resolution parameters)
https://git.archive.org/db48x/emularity_engine_v1/blob/master/cpc464.json

It causes the following problem running emularity as default.
https://archive.org/details/amstrad_abadia_del_crimen_64

By other side, Would nice if you know about how to pass the extra_args arguments into Archive.org in any meta tag because it's lack of examples.
The wiki seems obsolete since no reflect this emulator, seems the only popular old computer missing. Which is sad.

Proof and error is the only I have.

In archive,org forums they redirect me to [email protected] but nobody answered since a week. I hope to have luck in anyway.

Where are the examples?

The examples are not in the repo. Is that normal?

I am not able to run one example because of that.

Thanks for that awesome piece of technology!

Neogeo emulation

Hello and thank you so much for your amazing work with emularity.
By modifying your example_arcade.html file, I managed to load the Neogeo bios.
I'm trying to read some game too but now I'm stuck.
This is my working code:

  var emulator = new Emulator(document.querySelector("#canvas"),
                              null,
                              new JSMAMELoader(JSMAMELoader.driver("neogeo"),
                                                  JSMAMELoader.nativeResolution(320, 224),
                                                  JSMAMELoader.emulatorJS("emulators/neogeo/mameneogeo.js"),
                                                  JSMAMELoader.mountFile("neogeo.zip",
                                                                      JSMAMELoader.fetchFile("Bios",
                                                                                             "examples/neogeo.zip")),
                                                  JSMAMELoader.mountFile("mslug3.zip",
                                                                      JSMAMELoader.fetchFile("Game",
                                                                                             "examples/mslug3.zip")),
                                                  JSMAMELoader.mountFile("neogeo.cfg",
                                                                      JSMESSLoader.fetchFile("Config File",
                                                                                             "emulators/neogeo/neogeo.cfg")),
                                                  // JSMAMELoader.peripheral("cslot1", "mslug3.zip")


                                                )
                              )

  emulator.setScale(2);
  emulator.start({ waitAfterDownloading: true });

The commented part (JSMAMELoader.peripheral) is where I'm stuck.
Is it possible to link game rom files to "cslot1" ?
Do I miss something maybe ?
Thanks!

IALoader dosbox error?

Hello!
I tried to load over IALoader some dos games. For example, with this: var emulator = new IALoader(document.querySelector("#canvas"), "msdos_Alley_Cat_1984");.
But i've got an HTTP error 503 with CORS.

But when I use this: var emulator = new IALoader(document.querySelector("#canvas"), "msdos_Alley_Cat_1984/Alley_Cat_1984.zip"); all works fine.
May be it need to add detection of zip archives to get_dosbox_files function? Such as in get_mame_files function.

add a config option for handling the alt-enter shortcut, since the emulator may not be able to handle it correctly

Alt+Enter is only showing the game box in the middle of the screen.

Help with Loading Screen and Mobile

I've been working on a simple site with the EM-DOSBOX version. I notice that there is a black screen between clicking on the emulator and it actually loading the emulator, sometimes up to 30 seconds. This fine, since it (so far) eventually loads.

I'm curious how to implement a loading icon while DOS BOX does its thing up until the game arrives?

I'm also curious if there is any documentation on making this mobile friendly? When I load it on my iphone or ipad, it doesn't do anything.

Here is my site: https://www.grantcchambers.com.

Any advise or help is greatly appreciated! Incase you haven't noticed, I am new to webdev, but learning!

jsmess_set_mastervolume is not defined + MAME exception: Unknown slot option '""' in slot 'sl4'

The instructions in example_computer.html didn't work at first, with error

ReferenceError: jsmess_set_mastervolume is not defined

So I replaced messnapple2e.js with a version of mameapple2e.js compiled from the current build of MAME with emscripten, and got a different error

MAME exception: Unknown slot option '""' in slot 'sl4'

I changed the line

JSMESSLoader.extraArgs(["-sl6", "diskii", "-sl4", '""'])))
to
JSMESSLoader.extraArgs(["-sl6", "diskii"])))

After that, the machine successfully started and I was able to play HANG PERSON in Beagle Box.

console-1.txt

console log for the second attempt with a fresh compile of mameapple2e:

Emularity only unmutes the sound if a particular cookie is present

This is how IA remembers the user's choice, but may not be the best for everyone. I should leave the choice of mechanism up to the Emularity user by defaulting to unmuted, and making IA mute it during setup the same way it disables the splash screen delay during setup.

JSMAME web audio code no longer needed

The JSMAME web audio code is now in the MAME source tree at https://github.com/mamedev/mame/blob/master/src/osd/modules/sound/js_sound.js and compiled into the mame______.js.gz files, so setup_jsmame_webaudio() is dead code and no longer needs to be in loader.js. This happened several version cycles ago so there should be nothing left on archive.org depending on it.

cfg file in genesis don't work

First of all, thank you for your amazing work.
I would like to configure my own keys to genesis emulator, there a problem with defaults keys, ALT key in Firefox show the menu, I can use config file, but don't works.
For example, this is Wiz n' Liz running in genesis emulator (Internet archive example), it have a configuration file:

The content of the file is:

<?xml version="1.0"?>
<!-- This file is autogenerated; comments and unknown tags will be stripped -->
<mameconfig version="10">

            </port>
        </input>
    </system>
</mameconfig>

Z --> Button A
X --> Button B
C --> Button C

But in the emulator don't works, only CTRL, ALT, ESPACE key is working. ¿Is it a known problem?
I use this parameter:

MAMELoader.mountFile("genesis.cfg",
                                        MAMELoader.fetchFile("Config File",
                                                                             "genesis.cfg")),

I use this configuration in local, but config file don't work too.

Mounting the archive as a CD ROM drive (DosBox)

In the emulator it is possible to mount the archive as a CD ROM drive?
Is there a solution for such tasks?
