You can try to follow the ".stretch" video option in src/drivers/video.cpp.
OK I'll have a look

Another option is to wait, 31kHz is on the plan. :)
Really? Those are great news! Thanks for your good work.

I'm having trouble with getting a pixel perfect image on my setup. When I run FFVII with psx.correct_aspect_ratio 0, the scaling is correct, but the image is way off center. If I run psx.correct_aspect_ratio 1, the image is centered, but I get scaling artifacts (The "O" in SLOT 1, SLOT 2 is too wide on the save game select screen for example). Hope it's an easy fix! I've been banging my head against a wall for 5 years trying to get the mednafen psx libretro core to be pixel perfect in RA on my 15khz CRT—and it never is. Finally said you know what it's time to look outside RA. emu4crt is as close as I've gotten!

Try with superresolution, it seems only happens with native.

video.resolution_switch super

@Silmalik, i have noticed some differences on 1.24.3 vs 1.24.1.
In 1.24.3, for example in saturn with ss.correct_aspect 0 does not fill screen and with 1.24.1 it does...
In log i see:
MAIN - GameLoop - Game resolution change to 320x240, current game resolution: 0x0
 Initializing video...
VIDEO - Video_Sync - Output video resolution swithing: ON
VIDEO - Video_Sync - apply SUPER resolution settings - set to 2560x240
VIDEO - Video_sync - screen dest: 2560x240 - 0,0

If you need a picture i can attach some examples.

Thanks!!

video.resolution_switch super

Using super resolutions aren't ideal because it would homogenize the horizontal width differences I'm able to achieve with individual native modelines. i.e. how wide is the PSX's 320x240 on a CRT vs. how wide is the 368x240 mode. If I'm mistaken about this lmk.

Hi,

Correct_aspect_ration should be kept to 0, the screen do the correction by himself (kind of).
Some distortion when enabled is expect. So, we have horizontal centering issue then.

Do you have similar issue with other games ?

@psakhis  thank you for the support :)
About the ss issue, this might be related to some change made recently on official release, I will check that too if I can reproduce. Feel free to list some games if it doesn't impact all.

Yes, I tried FFIX at native res, correct_aspect 0 and it's off center, horizontally.

Hello,
I tried your mednafen's mod and i'm very impressed by the result !
It's my new way to go emulator for psx and saturn.
I tried a bunch of psx games (ntsc and pal) and all was perfect until i tried FF9 pal. I always get stuck on a black screen after the playstation red logo.
Ntsc version doesn't have this problem. I tried other pal iso of FF9 and i always get the same result, either native or super resolution.
For now it's the only game i can't launch.
Also, as screamingtrees, if set correct_aspect 0, i always get display to be off center horizontally. With correct_aspect 1, no problem.

Do you have an idea about what's happening with FF9 pal ?

Hi Dalba,

Your FF9 issue is probably related to copy protection.
Mednafen requires .sbi files along the untouched (not already cracked) iso files.

Sorry for off-center issue, will be fixed in the next release, in some weeks I'm afraid.

**EDIT - I was just installing it wrong, I had it set to "super" resolution in the cfg file but did not actually install the super resolutions from github, it's working now, thanks!

Hi all,
I am trying to get this to work on my 15 GHz arcade monitor and cannot figure it out yet and was hoping to get some help.

I've replaced the mednafen exe with the emu4crt exe

I've tried to edit the mednanfen cfg file to have the option for Video resolution switch (0, native or super) to be both native and super.
video.resolution_switch native

When I try the "super" config option: I get a black screen with white font up at the top and a purple swirl graphic. It doesn't look like it's losing sync but its not playing the game
When I try the "native" config option: I just get a blank screen, but does not seem like I'm losing sync

I've installed the below modes in VMM:

## Desktop ##

640 x 484 @ 60.000000 desktop

## Redream ##

640 x 240 @ 60.000000 redream

Hello,
Do you plan to update emu4crt to the latest 1.25 unstable or do you prefer to wait for a future version ?

Hi Dalba,

Yes, I have no concerns with Mednafen beta releases, I just miss some time to invest into the project at the moment.

I understand, no problem ! I think it's sad that your work is not integrated by default in current release of mednafen ! For an emulator looking for accuracy, what you have done is what create a big difference when you look for this way !

Thx! I notice the same diferent H Overscan differences vs 1.24.1 version, it seems disabled in newer versions.

I attach two logs from Astal on Sega Saturn.

PD: On native resolution, H Overscan works well on 1.26.1 too. Only "fails" with super resolutions.

Well, unfortunately, the logs are not great help in this case.

I can reproduce something: the image is correctly centered but there are some vertical black bars around, is this your symptom ?

Exactly, this it's the "problem", i see black bars around with all versions upgraded from 1.24.1, always with super resolutions.
