There's a lot that you need to go over and learn when first dealing with MAME. You should start here and move forward into the docs as needed.

@paulmdickey

We really need to know more information about your setup. The required info is detailed at https://retropie.org.uk/forum/topic/3/read-this-first

Take special care to note if you're using the Atari800 emulator, or lr-atari800.

Oh my god! Yes, there is! None of them are installed, but I can install the ones I want! Thanks so much, you guys!

@ithortureu alternatively you can just use a program like WinSCP to add roms etc.

cool thanks @quicksilver, I figured as much. I rarely add games so this kinda threw me off esp will all the permissions problems I created for myself moving from 4.3 to 4.4.

@nightfire

/opt/retropie/configs/n64/mupen64plus.cfg edits the standard mupen64plus emulator settings. At my level of expertise(or really a lack thereof) I am unsure how the cores are separated but the es_systems.cfg also lists editable extensions and I would presume if the mupen64plus.cfg doesn't also affect the libreto version, then this probably does.

I base my info off of exploration and reading the docs : https://retropie.org.uk/docs/Nintendo-64/ ; so I could be wrong.

Editing resolv.conf will always be temporary, I believe. The system overwrites/edits resolv.conf at times so changes may not/probably won't stick. Unless you manually set an IP address on the Pi, you should be getting whatever DNS servers your router (or whatever device is the DHCP server) is set to hand out.

I have similar problem. I thought its my adapter to the monitor. I use a dongle for keyboard too. What was the interval when you got this screen freeze? I get it maybe once in a hour. Maybe its a different story on my side.

Thanks Mitu!!

It seems that adding/enabling these lines in the config.txt fixes the problem

sdtv_mode=2 #My tv is PAL
sdtv_aspect=1 #4:3
audio_pwm_mode=0
dtparam=audio=on (this one is enabled by default)

Please add more details about your system as requested in https://retropie.org.uk/forum/topic/3/read-this-first.

Thanks guys, it was the case power

@boxdrop My buttons are configured to certain keys, so it'll hopefully work.

@pandamkii You don't unzip MAME roms, this is the way they're distributed they'll not work otherwise. If you're considering adding MAME to your setup and you're a beginner, then please read the Quick Start and the topics linked on that page. It will answer most of your questions and will help you understand how MAME rom(set)s work.

@mitu

Thank you SOOOO much. You're amazing! :-D

@quicksilver Awesome, thank you for the tip and info!

@jonnykesh you are right. I am an idiot. And i set that every time i set up a pi so i should have remembered that.

I don't think that it is specific to the Xbox dongle. I am having the same issue and found this on the rpi github. It looks like the kernel is having a hard time with USB hubs.

F/W 4.14.x causes dwc_otg_handle_mode_mismatch_intr:68: messages on boot with C-Media Electronics Inc. USB PnP Sound Device

I tested this with success. But I had to set dtoverlay=dpi24 and dpi_output_format=6 to fix some incorrect colors and use the below NTSC 320x240 timing line:

hdmi_timings=320 1 23 30 34 240 1 4 3 15 0 0 0 60 0 6400000 1
