Announcing Jnes for Android!

January 2nd, 2013 by Jabo Jnes comments: 55
Jnes is now available for Android 2.3 platforms and higher on Google Play. This is exciting for me as it is the first platform I've ported Jnes to in the many years I have been working on it. I decided to port Jnes as I have been using Android devices for about a year now, and it has become apparent that there is probably more people using these mobile devices than Windows computers. There are many of the same features in the Android version, with more to come. It just got added to the store yesterday I'll be posting screenshots here as soon as I can.

This is great news, I've been using another emulator on my Android device but I like the way JNes is. I hope coverarts do work for Android, I can't get this working on my Windows 8 PC (not tried on other Windows OS's thought)

I've modded my USB Nes controller to a NES Controller with USB stick inside it for if I do have my tablet, so Jnes is just in time!

Cool thanks I hope you do check it out, Jnes is new to the Android market, cover art is a feature that is planned for the near future as you can tell from the current screen shots it's part of the current layout.

“  Hello. Can u create jnes emul for winphone 8 ?

I'm not opposed to it, it would certainly be easier for me since it is a windows platform, however I would like to see if the Android version is well received first.

I wish I could try it on my tablet... the first is, it's 2.2.1 and it download no more memory won't return and USB is disabled (same for SD cards).

Could you also make one for the Symbian phones? I have a Samsung Omnia HD, and it would be great if Jnes is also compatible for the Symbian system then I can play NES games too when the pc isn't available

But of course, let's see if the Android version suits well for the users

Does anyone else have the issue of the emulator starting to run choppy after about thirty seconds of running the game with sound and tripple-buffering turned off in fullscreen mode? The game runs fine with tripple-buffering turned on, and my computer is well beyond the system requirements. In fact, the emulator runs fine with tripple-buffering turned off as long as the sound is also off. The problem only happen with tripple buffering turned off and sound turned on, which is my desired configuration.

I'd like to be able to run the game in full screen mode with tripple buffering turned off in order to avoid the input lag associated with vertical-sync.

Will the bugs be fixed in the Android version? Right now the star wars rom doesn't want to play, it stays on a black screen after hitting 'select' on the death star. Can't change characters or anything. sigh.

Any chance of this coming to the Amazon app store and working on the Kindle Fire as well as other Android devices? This is good but that would be even better.

It's hard to say, it depends on whether I come across a Kindle Fire to play around with and what the Amazon store policies are. Right now the focus will be on the Android version.

Hey Jabo. Just updated my review in the Google Play market.

I've enjoyed that you've been putting out updates for JNES on Android. Things seem to be coming along. But... We seem to be having a few issues here and there now with performance.

I'll just paste what I said in my review.

---
PERFORMANCE degraded after updates. No options.
[REVIEW EDITED/UPDATED: 14FEB13 4/5 --> 3/5 - Jabo continues to be responsive and is still working on issues.] We're making progress...but seem to be taking a step back as well. PROS: Controller issues seem to have been resolved. My genuine SNES controller works on USB2Go. My Red Samurai (bluetooth) works. JNES seems to have perfect sound compatibility. (Something Jabo has always been great about.) CONS: Performance WAS perfect but, after updates, is now taking a severe hit. Seeing issues with screen tearing (15% down the screen - from the top). Also some frame rate drops and refresh/frame skip(?) issues causing artifacts and/or 'transparency' (e.g. spawn invincibility in Contra) causing objects to be invisible. Settings continue to be VERY basic for now. (No tweaks or performance options available...yet.) The only options to adjust are: "Enable Stereo Audio", "Enable Virtual Gamepad" and "Enable Touch Zapper." I've been a big fan of Jabo's works for some time and have no doubt that this emulator will eventually become top dog - AS USUAL. Make sure you visit his site (jabosoft) and give feedback! Community think-tanking is a great way to make this the best NES emulator! (^_^)
---

I'm afraid that the performance hit really threw me a curve ball. I didn't expec that. Especially on my S3.

I hated to do it but...that prompted me to bring it down a notch to 3 stars. Sorry man... Just being honest. It's not to say that it's bad. It's just the current state of the app from my own perspective. (Yeah. I feel kinda bad.)

If you have any questions or want more specific info, let me know and I'll get it to ya when I can. I want to help however I can.

Some basic info and side-notes: I am using a well-maintained S3. I tried disabling WiFi and Bluetooth with all other apps killed. I also tried after a reboot with no foreground apps. Still having issues.

To be more specific on performance:
- There is a frequent screen tear about 10%-15% of the way down the screen from the top.
- When playing Contra (my usual test ROM) your character is supposed to appear as 'flickering' or 'invisible' when he first spawns. Instead, you hear him spawn but there is no trace of him until the spawn invincibility effect wears off. After that, there is a solid image of your character. It's as though spawn invincibility is caused by alternating "On" and "Off" frames of the character...and the screen is only displaying the "Off" frames until the spawn invincibility runs out.

^ Did that make ANY sense?

Also having issues with what appears to be dropped frames. It's a bit laggy.

Anyway... That's what's going on here.

Just thought you might like to know. I can't complain and not provide info that might help. I WANT to see this at 5 stars! (^_^)

Absolutely made sense thanks for getting in touch with me, you can always email me through the google market as well if you like, and yes posting here does not require registration currently.

As to your problems with tearing and performance, I'm aware of them as well, there is a major update in the works actually, working on it again this weekend. The update you reviewed was for a user who was having random IO Exceptions during rom enumeration. Anyway I was going to drop you an email after reading your updated review, glad we could share the information here, the ratings do matter and I want the emulator to work properly

Just wondering.. what happened to the compatibility? I downloaded this before on my Galaxy S2 and it worked fine, but now Google Play market says that it's not compatible with any of my devices, including the Nexus 7.

“  Just wondering.. what happened to the compatibility?

Not sure what you mean, but more recent versions require OpenGL, however every popular device made in recent years supports that.

I took a look in the developer console for Google Market and all Samsung Galaxy S II phones are supported, as well as the Nexus 7 - I actually happen to do all my testing on a Nexus 7. Are you running stock firmware? Send me an email through the google market and I'll see what I can do to help you further.

“  Thank you for getting back to me. I have a Galaxy S2 Lte edition, stock rom. I should probably mention also that im in South Korea

This is probably because the app was not published in South Korea (I dont speak Korean so I wasn't sure if I should do that). I've updated the store to allow users in South Korea to purchase now.

“  The Ouya is Android Based. IS it possible there may Jnes Support for that?

I've been wondering that myself with all the buzz around Ouya. Jnes is published in the Google Play Store, and I can't tell if Ouya will be using that for application distribution, if they do then you should have no problems finding Jnes.

“  Where do you put the pics for the cover art. I see no directory in ES File Explorer created by Jnes.

Artwork is downloaded so there is no place you can copy new artwork unfortunately. New artwork is added almost on a daily basis so feel free to refresh Jnes once in a while to make sure you have the latest cover art. It's also important to make sure you have verified GoodNES roms, some downloaded games have bad headers for example.

If you have a particular game you are concerned with feel free to send me an email through the Google Market page for Jnes and I can try to work out why it is does not have cover art for you.

Cool those are good ideas I'll add them to the wishlist.

I'm always trying to improve the built in artwork, it requires you have verified known-good ROM files, just thought I'd mention that. Additionally if you find anything that looks wrong please let me know.

Jnes for the Android is great! I recommend using an MK808 Mini Stick to plug in the back of your tv. Hook up a wireless controller and enjoy.

I hope to try the Kim(online play)thing one day.

Hi, Jabo!
Can you add Dendy-mode (PAL/NTSC Hybrid) to JNES Android (and Windows) please?
This mode allow to run most of NTSC games (Jap, USA) on 50Hz PAL, with correct DPCM sound pitch also.

Here is CORRECT and enough information about timings:

NMI info:
http://wiki.nesdev.com/w/index.php/NES_2.0#TV_system
http://forums.nesdev.com/viewtopic.php?p=81513#p81513
pAPU tables (Noise, DPC??) are same as NTSC:
http://forums.nesdev.com/viewtopic.php?p=91333#p91333

And here is my very old topic (it's not necessary).
You can listen sound tests and look at oscilloscope
http://forums.nesdev.com/viewtopic.php?t=5070

Nintendulator, Nestopia, puNES, Retrocopy, Nesicide and MyNES 5 already support dendy-mode.
Nintendulator name it as "Hybrid".

How-to-test dendy-mode:

First ROM is Battletoads and Double Dragon (U).nes
It must look like: http://img705.imageshack.us/img705/7139/animated.gif

Second ROM is Journey to Silius (U).
Pitch (4 channels + DPCM) must be like: http://www.fileden.com/files/2012/4/10/3290288/Dendy%20-%206527P%20-%20Raf%20World%20%28J%29.ogg

Hi Khaled, I've enabled purchases from your country. You can also email me from the Google Play store.

I try and limit the countries Jnes is available in as I can't communicate with users in every language. However if someone asks I generally just allow them. Let me know if you can download it now on your Android device.

I downloaded the jnes on my tablet and it is freaking fantastic! I do have a question, though. Granted, I will fully admit I am nowhere near tech saviee but I have found that USB based controllers are not working for the games. I've tried all the output options and although they work while selecting a game, they quit working as soon as the game begins. Are we stuck using the touch pad on the screen? Help!!

I'm having an issue that suddenly occured when I loaded a game in "The guardian legend". As soon as i start the game it seems the d-pad is stuck on Up. It only occurs in this game and it doesn't matter if it's a new or loaded game. I have tried reconfiguring the keyboard, Nothing... Any ideas?

Jnes for Android supports external USB controllers - to use them you have to go into the settings page and scroll to the bottom, select the player 1 config - change the drop down from touch gamepad to attached devices. If you still have trouble let me know, feel free to email me as well through the app or google play if you still have trouble

Reconfiguring the keyboard? are you using Jnes for Windows or Android?

Hey, Jabo! Why not add bilinear filtering to Jnes Windows version just like on Android?
2014-03-15 at 18:49 #46

Posts: 352
Jnes for Windows should have bilinear as well. The default renderer option lets your video card perform the resizing, this is suppose to be bilinear or some equivalent that is hardware accelerated.

Choyo
Reader

Well, At first, Jabo, thanks for your reply:), but anyway prior to Windows Vista, the bilinear filtering may work like a charm. But posterior to that, it does have a pixelated effect which is very annoying... The only way to solve this problem at this time is to try to use an app called DXGL.

No problem that's kind of interesting. I've seen that happen with legacy graphics hardware. Like if a newer version of Windows doesn't support your video card, the compatibility drivers generally do not implement bilinear filtering.

What graphics hardware are you using? perhaps updating your graphics drivers might be the solution. I can consider adding a real bilinear filter in the future, but truth be told the filter itself is quite ugly, have you thought about just using another filter instead?
2014-04-11 at 07:04 #49
Choyo
Reader

LOL, thanks in advance! I prefer bilinear filtering plus another filter effect and I guess the missing bilinear effect is due to the obsolete DirectDraw API(Maybe considering changing into newer Direct3D9 or Direct3D10). It's a shame that Only WinXP can do this mojo automatically though. ))) BTW, my video card is ATI Radeon HD4330.

Gamestick is now open to emulators, however no one has stepped up and released one on this portable android console. Would it be hard to port it from Google Store and sell it on Gamestick?
The JNes would do well on there.

“  I hope the JNES gets put on the Gamestick.

I wish I had the time, unfortunately there are a few of these Android consoles that to use their own store instead of Google Play, it puts developers in a tough spot to support all of them. My suggestion would be to ask them to support provide their users with access to Google Play somehow, otherwise it might be a bad investment.
