I can't play other games... for example Thumblepop!

[ziogoku]

Hi, I'm trying to launch Tumblepop but I can't do it.

The example of arcade: example_arcade.html, exaplains that we need to download the emulator and rom for game Targ, so I download mameexidy.js and targ.zip , and it work correctly (If I launch it from web server).

I try to change parameters to start Tumblepop, I found on https://archive.org/download/emularity_engine_v1/ the file tumblep.json:

`
name	"Tumble Pop (World)"
arcade	"1"
js_filename	"mamesupbtime.js.gz"
bios_filenames
0	""
peripherals
0	""
native_resolution
0	320
1	240
extra_args=
0	""
driver	"tumblep"
wasmjs_filename	"mamesupbtime_wasm.js.gz"
wasm_filename	"mamesupbtime_wasm.wasm.gz"
file_locations
mamesupbtime_wasm.wasm	"mamesupbtime_wasm.wasm.gz"

`

So I download mamesupbtime.js.gz as emulator from that site and put it on emulators/jsmess.

So I download rom .zip and put it in a path.

The code in the html is: var emulator = new Emulator(document.querySelector("#canvas"), null, new JSMAMELoader(JSMAMELoader.driver("tumblep"), JSMAMELoader.nativeResolution(320, 240), JSMAMELoader.scale(3), JSMAMELoader.emulatorJS("emulators/jsmess/mamesupbtime.js"), JSMAMELoader.mountFile("tumplep.zip", JSMAMELoader.fetchFile("Game File", "ROM/tumblep.zip") ))); emulator.start({ waitAfterDownloading: true });

(I added also the wasm)

When I launch I obtain that it load all resources, work untile open graphic canvas with: Loading Machine (0%)... it is died.

This is the console log:

Some idea????

Hi, I am also impressed with the Emularity project and, whenever possible, try to understand it more deeply. I was mainly engaged in game consoles, but arcade machines are also interesting to me. I launched both games that were mentioned above - both start perfectly. Here is a snippet of code to launch the second game. If it is not enough, then I will try to indicate more details. Good luck to you.

var emulator = new Emulator(document.querySelector("#canvas"),
    null,
    new JSMESSLoader(JSMESSLoader.driver("tumblep"),
        JSMESSLoader.nativeResolution(320, 240),
        JSMAMELoader.scale(2),
        JSMESSLoader.emulatorJS("engine/mamesupbtime.js.gz"),
        JSMESSLoader.emulatorWASM("engine/mamesupbtime_wasm.js.gz"),

        JSMESSLoader.mountFile("tumblep.zip",
            JSMESSLoader.fetchFile("Game File", "roms/tumblep.zip")
        )
    )
)

Thank you Leonis, I'll try and will know you if you resolve my problem!

[ziogoku]

Hi again Leonis, I'm traing to use your code but it give me error: Uncaught SyntaxError: Invalid or unexpected token mamesupbtime.js.gz:1

This because I used mamesupbtime.js.gz without unzip file. Is correct?

[ziogoku]

Ok, news: Now Tumblepop start! But for this I need to unzip the gzip files to .js!

Now another question: there is a mode to use directly the .gz files without unzip that????

[LeonisX]

I use magic in .htaccess file in root directory of web server.

I had to move the emulator storage to a separate subdomain, because this solution conflicted with server optimization aimed at the quick distribution of static files.

AddEncoding gzip .gz

RewriteEngine on

RewriteCond %{HTTP:Accept-Encoding} gzip
RewriteCond %{REQUEST_FILENAME}gz -f
RewriteRule (.*)\.wasm$ $1\.wasm.gz [L]

RewriteCond %{HTTP:Accept-Encoding} gzip
RewriteCond %{REQUEST_FILENAME}gz -f
RewriteRule (.*)\.js$ $1\.js.gz [L]

<FilesMatch ".+\.wasm.gz$">
ForceType "application/octet-stream"
</FilesMatch>

<FilesMatch ".+\.js.gz$">
ForceType "text/javascript;charset=UTF-8"
</FilesMatch>

<FilesMatch ".+\.wasm$">
ForceType "application/wasm"
</FilesMatch>

The idea is to return the already packed GZ file, but with the correct headers (Content-Encoding: gzip and Content-Type) - the browser, seeing this header, will unpack the archive itself. At the same time, resources will be greatly reduced: you do not need to pack the emulator on the server side each time and you do not need to overload the Internet channel much.

Unfortunately, I’m not a great specialist in this, the code was born after hours of searching among examples. I hope it will be useful.

[ziogoku]

mmmm.... I'm using IIS and there is something like that for IIS, but it not works :(

[LeonisX]

.htaccess is the configuration file for theApache HTTP server, I hope that there is a similar solution under IIS, I described the principle in the previous message, you can return the compressed file, the main thing is to specify the correct header so that the browser unpacks it automatically.

[ziogoku]

Ok Leonis, you are very gentle and I thank you! I try to convert the .htaccess in a web.config , using IIS tools for URL rewrite, and it results: `

`

But this doesn't work :(

I'll see with an apache server, maybe will be better!

Thank you for the moment!

[db48x]

I'm sorry that I didn't see this earlier; my spam filter seems to have gotten above itself.

Thank you @LeonisX for your help here, I really appreciate it.

@ziogoku, I don't know anything about IIS specifically, so I don't know if that configuration is correct or not. It sounds at the very least like you know what needs to happen, and since this was filed in January I suspect you might have gotten it working since then. I'm going to close this issue, but don't hesitate to open another if you have another question!
