is there anything like this but for nds? i have done some research but no luck. Something were you just put in a save and a game file and boom you play. i have tried emulator.js but i couldn't fine a web server that worked :(

This should work

<script>
function save() {
	let gba = this.gba;
	gba.pause();
	window.localforage.setItem("state", Serializer.serialize(gba.freeze()), function (err) {
		gba.runStable();
	})
}

function load() {
	let gba = this.gba;
	window.localforage.getItem("state", function (err, value) {
		Serializer.deserialize(value, function (out) {
			gba.pause();
			gba.defrost(out);
			gba.runStable();
		});
	});
}
</script>

<button class="bigbutton" onclick="save()">SAVE</button>
		<button class="bigbutton" onclick="load()">LOAD</button>

However we are running out of room in the ui, so some ui designs make be helpful

Hey all, looking to create the UI for both menus this week. What kind of information and menu items need to go into both of these menus, please see current designs.

Are there any suggested features that would be nice to have?

Allow users to enter a URL that points to a ROM to load.

Users on mobile may have an easier time pasting in a link to a file on Dropbox or a personal server than browsing their device's file system. Same could be done for the save.

Also, allow the ROM URL to passed in via a URL query parameter. This would enable users to bookmark or "Add to Homescreen" an instance of GBA.js that would boot up that game right away. An additional URL parameter could also load a save.

Hello! I have a question that I couldn't find answered in the documentation. I am working on a GBA game and I'd like to publish it so that people can play it in the browser without downloading the rom file and clicking "Select" on https://gbajs2.com. Basically I'd like to know how to modify index.html so it automatically loads a rom from a preselected URL rather than prompting the user.

I'm sure this is probably obvious to someone with a cursory understanding of Javascript, but for the rest of us, it'd be really useful to have this documented. Thanks!

it seems that this project is so perfect! But is it possible to add some network api that let people link together through websocket? If so, that will be so great to play games like Shinning Souls 2.

The emulator has a cool visual debugging system however right now I don't think it works

Rom-based https://github.com/jsmolka/gba-suite

More comprehensive but might be harder to integrate: https://github.com/mgba-emu/suite

For just now set the baseline for regressions, however it would be nice if this set the framework for someone to work on compatibility.

Whenever you open a ROM, the "Upload Savegame" button disappears. Whenever I use the button before I open a ROM, it does nothing. Also, are the saves meant to be downloaded with no file extension?

Under the homebrew heading, there are multiple custom open source games - even something as simple as a flappy bird clone being loaded/available by default would make it much easier to check out your emulator (especially its performance compared to WASM projects)

There is a pretty good implementation of it here:

https://github.com/trentmercer/gameplayadvanced

I have been working with some of these changes locally. I do think the style of it could be improved. Also if there could be a way of allowing someone to drag their finger to change which dpad input they are putting in (currently only taps work)

@trentmercer are you interested in trying to merge your changes in?

What is the debugger and console? And how do you use it? Thank you!

A couple people suggested the ui could be improved:

• Mobile ui non existant
• A lot of buttons now
• Need a remapping design
• Possibly prepare a homebrew game to show off the emulator?

Hoping to start a thread where people can post some images of designs

See #10 for testing this functionality.

What it says on the tin. I'll put together a mock for approval.

I'm a private user.My school device use the browser that doesn't support local file browsing and downloading.Is there a method that can preload ROMs ?And can we use Cookie to save the game?

Not sure if the project has been profiled but that might be a good project to look into

That is, when I change the size of the canvas, the scale of the rendered image is not scaled proportionately. If I scale it to 0.5, only 1/4 of the half-size canvas is covered (the rest being a ghost of the last full-size frame). This gets in the way of adding a fullscreen button (since the image renders way off the screen).

Suggest having in-screen controller using for playing on mobile. We can create a new class to handle controls just like keypad.js

Hello. I was wondering if there is a way to use the saves in PKHeX? Thank you!
