That seems like a good idea to implement in the future! Should I have the screenshot immediately downloaded? Or did you have something else in mind?

I am trying to implement saving game state with screenshot display. When i try to read a file in the virtual file system along the path /home/web_user/retroarch/userdata/screenshots/rom-210621-190311.png, an error occurs.

You may have to put it on a short setTimeout.

I did save screenshot to file:
function takeScreenshot(){
Module._cmd_take_screenshot();
var screenshot_path = "/home/web_user/retroarch/userdata/screenshots/";
var screenshot_name = makeScreenshotFilename();
window.setTimeout(function() {
if(FS.analyzePath(screenshot_path+screenshot_name).exists) {
var file = FS.readFile(screenshot_path+screenshot_name);
downloadFile(file,screenshot_name);
} else {
console.log('screenshot not found')
}
}, 500);
}
function makeScreenshotFilename(){
var now = new Date();
var y = now.getFullYear().toString().slice(-2),
m = ("0" + (now.getMonth() + 1)).slice(-2),
d = ("0" + now.getDate()).slice(-2),
h = ("0" + now.getHours()).slice(-2),
i = ("0" + now.getMinutes()).slice(-2),
s = ("0" + now.getSeconds()).slice(-2);
return `rom-${y}${m}${d}-${h}${i}${s}.png`;
}

Nice! That works very well! I was planning on making a screenshot gallery feature, so that the user could browse their screenshots, and then download them whenever they want. Will be in the next update.
