NES Roms Will not Display saying not supported resolution

Jcnavyd

OK well to start I am VERY new to this so please to not beat me down on this. So I have Atari, SNES, And Sega roms and they all work fine. ONLY my NES roms say the error on resolution. I have deleted them and reinstalled. I have tried them on an other TV and they work. But for some reason they have issues on my main tv. Makes no sense. I have gone in and tried every resolution setting available with zero luck. PLease can some one help me with this?

@Jcnavyd I'm sorry but there is absolutely no useful information contained in your post that would allow anyone to even begin to try and help you. Can I suggest you post the information requested at the top of the page and throw in a few extra details about the TVs used and how these resolution errors were reported. Given that information hopefully someone will be able to help you out.

Sorry once again super new. The TV i am hooked up to is a Samsung UN55ES6500F. Says capable of 1920 x 1080 60mhz. I have ROMs for atari, SNES and Genesis and they work just fine. No issues. When I go to select any of my NES roms i get the real quick load screen, then black screen and my tv says none supported resolution and to check devices to change resolution type. I have gone into the pi setting and tried each other resolutions types one my phone with no chnage for the NES roms. I am using the latest version of RETRO Pi, not sure if this makes anymore sense or not

AlexMurphy

@Jcnavyd Yes, thank you. So the message is from your television. I understand now. With the Pi hooked up to the problem TV type tvservice -s into the terminal and post what it outputs here. It should be a single line. Press F4 to get to terminal from ES/RetroPie.

@AlexMurphy Sorry for the delay worked today. So the command response I am getting is as follows:
state 0x12000a [HDMI CEA (16) RGB lim 16:9], 1920x1080 @ 60.00Hz, Profressive

AlexMurphy

@Jcnavyd The same as me for the TV output so that is good. Can you please put in the command nano /boot/config.txt and copy the output, post it on http://pastebin.com/ and post a link here. Thanks. I should be around for the next few hours. WE will get this sorted!

@AlexMurphy Also as a Side note. I have noticed that when playing the other roms, ie Sega master system, snes, atari the resolution stays the same as the emulation stations. When I try to play a NES rom the resolution changes. Is there a way to control the resolution JUST of the NES roms that would differ form the other systems?

AlexMurphy

@Jcnavyd I see a few things.. Change this arm_freq=800 to this #arm_freq=800. Change this hdmi_drive=2 to this #hdmi_drive=2. Put a hash/pound before these lines. hdmi_group=1 hdmi_mode=16 so they are #hdmi_group=1 #hdmi_mode=16Do this then reboot. Let me know.

@Jcnavyd are you going into the runcommand that displays after you start a game? You can change the resolution there. It is also possible you set the one systems resolution in there to something your tv doesnt support.

AlexMurphy

@edmaul69 I put the TV model in a search engine. The TV is fine. It is full HD and capable of displaying what the Pi / Emulator is outputting, as are most modern TV's. Some are just fussier than others. Did you look at the config.txt file on pastebin? Some odd stuff going on there. I t looks like someone has tried almost every solution at the same time.

edmaul69

@AlexMurphy i see. he needs to turne safe mode off first of all. that is a huge issue and it wont ever display 1080 with it on. everything else looks ok

AlexMurphy

@edmaul69 She has it underclocked to 800MHz by un-commenting the arm_freq. line.

Jcnavyd

@edmaul69 How do I get into the run command once in a game? Sorry And I am paking changes to the config file now as outlines above and will post results

Ok So I am able to get individual roms to play on the tv if I go into the setting at launch of the individual rom. I had to go to "Select video mode for lr-fceumm + rom ()" Once I clicked on that the ones that wont play are set to default on " CEA-4 1280x720 @ 60mhz 16:9, clock:74mhz progressive" I changed it to "Cea-16 1920x1080 @ 60hz 16:9, clock:148mhz progressive" and the game will launch and can play. The only issue is that I have no audio while playing and it is not full screen. it appears to be 4:3 but this is progress. Thank you all for your continued help.

Jcnavyd

Ok have the audio working now. Last issue I have is that my usb Retro NES remote is all messed up. ie, b and a buttons are switched, select is starts. This causes issues when I cannot hold select and start to exit game. The remote works fine in other rom games except the NES. I have tried setting up several time in the input game pad set up and all worked fine on that
