*SOLVED* 240p per emulator (run command setting) possible?

@matchaman also here are the commands for tv service. i use putty to ssh into the pi to use commandline.

240p

sudo tvservice -c "NTSC 4:3 P" ; fbset -depth 8 ; fbset -depth 32; tvservice -s

480

sudo tvservice -c "NTSC 4:3" ; fbset -depth 8 ; fbset -depth 32; tvservice -s

I see, however it's possible to be done via runcommand which is simpler, doesn't give a momentary message and also safer for video themes.

In the past I tried several workarounds (very likely including your method) and when exiting a game, video themes had erroneous structure :/

Though runcommand isn't perfect either; as I mentioned before, if the config.txt mode is NTSC or PAL, then the game running in the same region's progressive mode will not go back to interlaced (unless it's at the opposite region).

@matchaman i never get an error message, so not sure what you get from other methods.

Edit:i think you are saying themes that have videos gets the erroneous structure? I wouldnt know as i dont use video themes.

@matchaman also with this method i use, it goes back to interlaced after i exit a game. All this is ntsc as i dont use pal at all.

I hate to resurrect an old thread, but I'll likely be going through the exact same process soon in an old PAL CRT.

Just to confirm, @matchaman , your TV is PAL and yet it works well with the NTSC 4:3 P video mode, is that it?

If you just used the sdtv mode to 240p you wouldn't have needed to change the individual emulators settings for them to display as intended but ES would have looked fairly bad, correct?

Just making sure I follow it.

Thanks!

@pjft Are you going to connect through RGB or composite?
Personally I use runcommand which is more versatile but it also depends on the method you're using. There is also a CRT theme (named "CRT" :) which works well without the need for 480i.

@youxia I was going for composite.

@pjft Then I recommend reading about these 2 methods first, the ES look is the least of your worries ;)

@youxia Thanks - I'll look into it!

I've been looking into this a bit recently. I find that the default settings look pretty good in 240p with bilinear filtering on, but I wanted to get really accurate results so I compared the real NES hardware output to the raspberry Pi composite out in 240p.

for NES my CRT likes
-240p screen format
-640x480 render resolution for the screen format
-717x552 (5 x -40 offset) retroarch scaling resolution
-bilinear filtering set to off

For SNES I use a 702x496 retroarch custom scaling resolution with a 12 x -8 offset and bilinear filtering on. Genesis looks pretty good with bilinear filtering on and standard 4:3 resolution
