@pibell90 said in A new resoloution option should be added to raspi-config:

@pibell90 Yeah I don't think that 720x480 has a DMT mode, so is there anyway to bypass that altogether?

You can create a custom video mode - see https://forums.raspberrypi.com/viewtopic.php?t=24679, which is aimerd specifically at this kind of scenarios.

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

@jamesfarnhamlong said in Retrotink U - Higher res ES and PSX games:

The 450x270 looks best, but I was wondering if it was possible to run one @ 720x578 to improve the picture a little. I know the TV supports this as I have an old Apple TV that uses this revolution. How do I write the hdmi_timing to make this work? Is there a calculator or something I could use?

Try this - http://eightvirtues.com/lakka/hat/RPi HDMI Timings Calculator and Core Docs.ods (courtesy of https://www.youtube.com/channel/UCtF_2HGXXPlUi1J0Euw1Qrw).

Is it possible to adapt this to run at 2x resolution so I can use the enhanced graphics in psi-rearmed. Is there a way to have this only affect psx game launching? Or would it then throw out all the other systems? Is there much point?

Maybe if you use the calculator linked above you can derive the correct HDMI timings to use. As for the effect on the other systems, you'll have to ask the author of those configs.

So going back to HDMI I'd have to remove/comment audio_pwm_mode=0

You can quickly toggle the option from a script or the console by these commands:

# make a backup of config.txt cp /boot/config.txt /boot/config.txt.backup # switch to "1" sed -i -e 's/audio_pwm_mode=0/audio_pwm_mode=1/g' /boot/config.txt # switch to "0" sed -i -e 's/audio_pwm_mode=1/audio_pwm_mode=0/g' /boot/config.txt

The lines beginning with # are comments and can be omitted. Mind the single quotation marks, they're important!

You could save them in convenient executable scripts in a (new) directory called "bin" in your home directory:

cd /home/pi # make sure we are at home mkdir bin # create the directory "bin" echo "sed -i -e 's/audio_pwm_mode=0/audio_pwm_mode=1/g' /boot/config.txt" > bin/pwm1 # write the first sed command to bin/pwm1 echo "sed -i -e 's/audio_pwm_mode=1/audio_pwm_mode=0/g' /boot/config.txt" > bin/pwm0 # write the second sed command to bin/pwm0 chmod u+x bin/pwm1 # make pwn1 executable chmod u+x bin/pwm0 # make pwn0 executable

Since $HOME/bin is part of the console's search paths for commands and scripts, you can now just execute pwm1 or pwm0from any directory to toggle the option audio_pwm_mode between 1 an 0.

Besides that matter, do you know that you can enable an experimental audio driver with audio_pwm_mode=2? It fixed an annoying static noice on my Pi.

@akafox This makes alot of sense. As I suspected, the TV is just slowly on it's way out.

And yeah, its more likely to appear when sitting on a static image. Therefore keep it moving with a game running!

CRT's are a dying breed unfortunately :(

@foxcek please read my last post. Can you take a picture of the tv screen when you hit the info button or change the channel to the video mode you are using? I want to see what mode its on. Plus a pic of the back of your tv's video hookups with and without the cables plugged in.

also check out RetroTink (retrotink.com). i've read a lot good things about it, and plan on getting a tink-ultimate model when they are released.

WIthout going into every game in MAME and doing per game settings for vertical and horizontal games, is there a way to set up all horizontal games with one setting and all vertical games with another?

Then when I'm in individual games, if they don't look right, I can tweak them but they'd generally be close to start.

From the videos it looks like it's just the interlacing flicker. Pretty much the same on my 576i CRT
