Help me beta test my NES remote play

Post by AsmCoder8088 »

I'm developing a way to remotely play my NES using a raspberry pi connected to the internet. Right now I have only one NES configured, and one controller, but hope to expand to multiple NES and controllers if this pans out.

It requires Skype to establish a low-latency video connection. I had wanted to use a browser plugin for the video but those are all high latency, so Skype it is.

If you are interested, here is the site:

And here are the instructions:

Just to clarify how it works.

Even though it uses Skype, the whole process is automated. That is, you click the "First player" button (after solving the Captcha) and a program I wrote running on a laptop updates the settings in Skype to receive incoming calls. The program then does a screen capture every 3 seconds and looks for when there is an incoming call, and answers it with video (in this case, the composite video from the NES, which is sent to a DVC100 video capture card to the laptop).

So after you click "First player" button, wait about 30 seconds, and then you can initiate a Skype call to "cedararcade@outlook.com" to receive the video. The game running on the NES is then playable via the browser web page, as your keystrokes are sent to a websockets server which in turn sends them to the raspberry pi, which then sends them to the NES.

Here is the block diagram:

Any feedback would be cool 8-)

I would estimate less than 1% of people have Raspberry Pis. Considering how few regulars there are here, you may be the only one with a Raspberry Pi. Just a guess.

Maybe you should consider going to a forum for Raspberry Pi users to see if anyone there will test your remote system.

From what I understood of his explanation, you don't need a Raspberry Pi to play, you just need a browser and Skype. I think this sounds pretty cool, but I didn't have the chance to try it yet. I still have to install Skype and remember my account information.

OK, just tried it. Turns out I had a portable installation of Skype that still worked. Anyway, everything worked fairly well, video and audio were pretty decent. The lag was about 1/3 of a second, and it didn't feel like enough to ruin Paperboy (although I'm pretty bad at this game even without any lag). I'm not sure this was the kind of lag you were expecting, but 1/3 of a second is probably too much for the majority of the games. Still pretty cool though, never thought I'd be controlling an NES remotely and receiving captured composite video through Skype!

That's correct, no need for the remote player to have a raspberry pi.

All the remote player needs is a web browser and Skype.

Tokumaru, thanks for testing it out. I actually think 1/3 second lag is actually not too bad, considering you are from Rio de Janeiro, Brazil and the NES is located in Oklahoma City, USA. I agree, I never imagined being able to play an NES remotely like this, but a week ago I came across a schematic that someone put together on how to interface a raspberry pi to make a wireless controller, and I thought, why not go one step further and make it connected to the internet? So here it is:

I'll be making more improvements to it as time goes on, but for now I'm wondering if anyone can beat my highscore of 12,000? :)

A couple years have passed and I decided to make a few improvements.

This latest version no longer needs the player to have Skype.

Instead, I rewrote it using WebRTC.

So now you can play the nintendo remotely in a web browser.

If you are interested in trying it out, here it is:

https://www.cedararcade.com

After clicking 'Take Control', click in either the brown or black region to ensure that the page has focus (otherwise it won't capture the keystrokes to play). Then press 'Enter' a couple times to start the game. The 'A' and 'S' keys on the keyboard mimic the 'A' and 'B' of the gamepad.

As a refresher, this is basically using a Raspberry Pi to control a nintendo over the internet, and I'm using a video capture card to stream the composite video.

It works good. First time I played the video turned to a blurry mess like the bitrate dropped, but after restarting it, it worked fine the rest of the time. Didn't seem like had any trouble playing the game with the lag. Kinda funny that I made it to the high score entry screen, and that's where the lag really became noticeable.

I played a round of PaperBoy. Seems to work pretty well. I can feel the lag a bit, but it wasn't horrible. The video stuttered a little bit too, but again not a big problem. Pretty neat.

It worked pretty well here too. The lag is very noticeable, but hard to measure accurately... about 1/2 a second I guess. Didn't get any stuttering or bitrate drops, the video was pretty sharp and smooth during the short time I played. Very cool!

I really, really suck at Paperboy though...! I wonder how it'd feel to play a game with a more responsive main character...

I tried either in firefox or chrome on linux but nothing was shown on the screen. I do not know if it's related to my location (japan), the network I'm on or the OS that could cause it to just show a brown screen and that's it. It can start and release but nothing else happens.

I will try it again tonight on a different computer.

Thanks everyone for the feedback.

It sounds like it seems to play pretty well if you're playing from the same continent. It is hosted in Oklahoma City, Oklahoma, USA. You can ping 104.154.165.231 to get an idea of what the lag would be like.

Haha, yes I agree that Paperboy is a bit tricky to play even under perfect conditions.

Any ideas for another game to try?

I'm thinking it might be possible to have a few NES systems and maybe a video switcher to choose between them, keeping them all running 24/7 so that high scores don't get reset.

That's very cool!!

It has a little lag, but I think it's fine.
I'm really bad at this game!
To tell the truth, I don't remember to have played it back on the day. :roll:
For me it only worked on Firefox, not on Chrome.
I'm using Ubuntu 16.04.5 LTS 32 bit from Brazil.
You can take a look at my neighborhood with the coordinates on my profile. :-)

Maybe you could try some homebrew games on it.
Could an option to use joysticks be added?
I don't know if this can be useful, but I'm posting the ping statistics:

I did try at home and now I can see a picture (Windows 10 machine), which mean the issue was when loading in a browser on a linux platform, possibly. I don't know the cause yet. I will check if any errors in the console, if any. Works on mac too.

edit:

Last message from the console in the linux box:

Code: Select all

ICE failed, add a TURN server and see about:webrtc for more details

In my case it worked well on Linux, using Firefox 61.0.1.
I tried it on Chrome and it didn't work.
Also, it didn't work on my Android phone.
It poped up a window explaining that it won't work on mobiles because the keyboard is needed, wich I think is totally fine.
