Ok so basically I Love DS games and I was wondering if you can add in your emulator the DS games and while I understand it's laggy, I was wondering if its possible for the DS games to run more faster (I play on Chromebook) and an idea I had was to make it were you can make the frames go higher or lower as an option

Is the file for the cores the .js or .wasm? And how did you find the buildable cores?

I got to about where you are building mupen64 for web. Another project you might be interested in is https://github.com/nbarkhina/N64Wasm/ they took the old parallel libretro code and used SDL openGL baked into emsdk.

My question is if it is possible to basically go back in time just forget about Glide and use CPU cycles to get something working for N64? It looks like in the most current versions everything is tied to threading and as far as I can tell with all the building I have done enabling PTHREAD in retroarch and using workers is a big overhaul to the codebase to enable shared memory arrays.
I got the interface to load using proxy-to-worker, but any core launching from there will just crash.

I have not had any luck getting the parallel core building and working with angrylion RDP on my own, just wondering if it is something you have looked into? I am mostly interested to see if it produces something playable with a modern CPU despite the lack of threading.

Also unrelated to this issue, it looks like to get mobile compatibility the missing piece is overlay support in:
https://github.com/libretro/RetroArch/blob/master/input/drivers/rwebinput_input.c
It needs touch mapped like they do for mouse:
https://emscripten.org/docs/api_reference/html5.h.html#touch
https://github.com/libretro/RetroArch/blob/master/input/drivers/rwebinput_input.c#L261-L279
Then referenced properly in input_overlay.
Alternatively elements can be rendered in the page separate from the canvas.

Basically I have gotten as far as I believe I am technically capable of porting cores over for self hosted web and seeing if you may have anymore insight on continuing to fork off some of these cores to something usable for web.

Not that much of anything really just want to use this while on my school computer please

Hello there BinBashBanana!
I’m back from the dead and to suggest a core!
Pokemon Colosseum is really taking the title as the hardest Pokemon spinoff game.
Not much here to say really.
Thanks for reading this and I hope you add it in for 6.6 or possibly 6.7.
-ChaoticDX

is this possible?

please

Sega CD emulation doesn't work because its impossible (as far as i am aware) to add a Sega CD bios to the Genesis Plus GX core. It's possible to load an image of the Sega CD bios but I can't load the bios image into the core before playing the game. Is there something im missing here?

Would it possible to use pre-existing save files from other emulators? I have a .dsv file and want to import it.

please

I heard that you don't plan on adding 3DS games and while that sucks an idea came up in my head I was wondering if you could stream it by the Cloud and while we're at it could you make an alpha for a 3ds Core and we can test how it runs,

Btw do you think you can add local or online multiplayer on MelonDS

Thanks for reading this :D

Attempting to use the emulators on chromebooks, and even though online versions of the emulators work, downloading the file and using a core from index.hmtl does not work. Any help on this?

like "psx"

and can i using you cores in my reto "retroarch-web"

retroarch.nenge.net

it says cannot push null or empty core path this is on safari mac and prolly says the same thing on safari mobile
then it just never loads

I downloaded a rom for "Final Fantasy 7" from the site "CDromance" and whenever I upload the directory to webretro, it does not load, however my tekken 2 from for ps1 does load which has a larger file size does load. CDRomance is pretty reliable so it does not seem to be the issue.

I was wondering if you could add ps1 support to webretro? Really wanting to play Metal Gear Solid

retroarch Merge file is incomplete，make wasm error

How do I adjust the auto-save feature to save more often/save save-data manually?

So my school has recently blocked all access to github pages, which means I won't be able to use any sort of github related item. I was wondering if you could download the entire webpage and view it offline? If someone knows how, please tell me. Thank you

the emulator itself is stuck in 4:3. like the actual retroarch thing itself. is there a way to fix this?

I knew from HU that you were developing a ds emulator for it, so i wanted to know; is melonDS coming out anytime soon?
Thanks!

When run locally, webretro just hangs on the "Loading" screen. Do you (@BinBashBanana) know what might be wrong?

I'm really looking forward to playing arcade games in browser. :)

just wondering, i wanna play ultra sun/moon

i've been a great fan of this emulator but theres one thing that makes me want to kill myself
i can't play pokemon nds games because they're too laggy
can you add bigger file support
the game still works but at like 10 frames
thanks
pokemon is life

maybe make it where the retroarch menu would open after you select a core, then you can select the content, change settings, ext.

Hi! Is there any way to get the result of calling _Module.cmd_take_screenshot() method?

Just a heads-up.

I test your more system-cores,they only run in Microsoft Edge/Chromium

can not run in mobile (ios)!

in the js ,here nothing retrun.

• WebAssembly.instantiate(binary, info)

    function instantiateArrayBuffer(receiver) {
        return getBinaryPromise().then(function (binary) {
            return WebAssembly.instantiate(binary, info)
        }).then(receiver, function (reason) {
            err("failed to asynchronously prepare wasm: " + reason);
            abort(reason)
        })
    }

would it be possible to detect if you're on mobile and then have some controls overlayed?

Hi! Is there any way to change configuration after starting emulation? I need to change gamepad configuration. I know that this can be done through the menu, but can it be done through javascript?

Is it possible that we could add more systems such as the wii / gamecube (dolphin emulator)

I'm trying to embed it, and I can't figure it out. if you can help me because it just shows the 404 error as it can't find the file.

1. Is it possible to make this as a chrome extension?
2. How do you remove/add cores

I know its the summer, but im just curious on the release date of the update

I test the "mednafen_psx_hw_libretro" not well

• can not "fast-forward"
• i play the "Dragon Quest Monsters 1 & 2" lost my character, I seem to remember that the ios app seems to have this problem too.
• state save very very slow. (https://github.com/nenge123/retroarch-web/deployments/activity_log?environment=github-pages)
  • test
    (https://github.com/nenge123/retroarch-web)

can you can bulid the "pcsx_rearmed_libretro" ?

Not sure if this can be solved/answered here, but: Paper Mario crashes (the emulator, not the game itself) due to a "null function or function signature mismatch" . Based on a bit of testing, the time at which it does this seems to vary based on settings, but is consistently no later than the beginning of the very first intro cutscene. Is there any change that can be made to settings or the core to fix this? Failing that, is there some way to compile another core (i.e. parallel-n64) and drop it in here to see if it works, or is there support that needs to be manually added to each core? (I really don't know much about libretro or emscripten for that matter)

pls detail instruction 👍

Random request, I'm currently working on a Discord bot to play emulated games in a co-op fashion. I'm integrated WasmBoy, and currently digging through the source code here. Any pointers on how to get thise running in a headless mode, i.e., as a Node.js service?

Please allow me to express better in my native language!

下面代码是原来的鼠标"mousedown,mouseup,mousemove"

mednafen_psx_hw_libretro.js

    function fillMouseEventData(eventStruct, e, target) {
        var idx = eventStruct >> 2;
        HEAP32[idx + 0] = e.screenX;
        HEAP32[idx + 1] = e.screenY;
        HEAP32[idx + 2] = e.clientX;
        HEAP32[idx + 3] = e.clientY;
        HEAP32[idx + 4] = e.ctrlKey;
        HEAP32[idx + 5] = e.shiftKey;
        HEAP32[idx + 6] = e.altKey;

由于我使用了

• <canvas id="canvas" width="960" height="720"></canvas>
• widthNative:960
• heightNative:720
• getBoundingClientRect:{width:414,height:896}
• 因为"canvas "越大越清晰!

导致问题

因为大小不一致,会导致鼠标指针异常!所以使用以下代码修复.

• 但是移动端出现问题
  • F12
  • edge浏览器,
  • 移动端模式
  • 指针异常,不论我如何调整总有差异,不准确.

    function fillMouseEventData(eventStruct, e, target) {

Whenever I upload the rom for Metal Gear Solid on my Chromebook, it crashes and I have to power refresh. Sometimes it gets to the "Select Master ROM screen" before crashing, and when I select a .cue or .m3u file it crashes. Can my Chromebook just not run games made on the Playstation, or is there a fix for this? I really want to emulate the Playstation on my Chromebook.

Ever since 6.4v, when I play fast forward on mGBA (haven't tested it out on other systems), it won't, well, go fast. It plays at normal speed with, or without fast forward toggled. This may be a problem on my end.

you know how in the embed example html file it has a small embed? how do i make it just the game and nothing else?

I'm interested in launching a rom and when the user navigates back to the main page, I want to send either a save file or savestate back with them to do further processing. Is this possible or something that can be added without much difficulty?

some of the textures on the ps1 emulator glitches out, i can post a screenshot of it doing it if you want,

I was wondering If i can have this play one specific rom on a specific page without having to select one like JSNES does. If so, walk me through it.

It seems the commit 65ab91cfc5db110d3236ac8b6148e7e935b46d18 (link) broke some shaders for the n64.

I tried running mario kart 64, It seemed to run fine until it had to render the level screen and it seemed that the entire UI just crashed, nothing would render. I backtracked to see what broke it and it was in this commit. It worked in the commit before this (last working commit - 526f18b06058a68b405488549773fe47ebf4af61 (link)

I tested using githack: https://raw.githack.com/BinBashBanana/webretro/526f18b06058a68b405488549773fe47ebf4af61/index.html?core=mupen64plus_next

I ran some testing - webgl2 did not break this

Could it be possible to have the PlayStation portable core in the future?
