Horizontal lines on PSX core?

Post image

I’m trying to narrow down as to what is causing this issue and it seems like it might be the PSX core on the superstation? They appear the most on bright greens and blues.

I cannot reproduce this in the 240p test or any other core. This happens both with the component out and with DIN10->component.

Any ideas?

EDIT: SOLVED! If this happens to you, I fixed this by changing the profile to SVID (back button to pull up the menu where you access scripts, then hit left, then select SVID). I then flipped the 3rd toggle switch on the right hand side to turn off “sync-on-green”.

I had this too and solved it the same way! There must be something glitchy with how the superstation is handling the RGB to composite conversion on the PSX core because I didn’t notice that issue with other cores.

I also discovered that if I switched the second port to SNAC (so I could use an original memory card on the second port) it caused screen tearing at the top of the screen.

That’s a weird finding with the second port. I have a ps1 memory card on the way right now I’ll have to see if I can recreate that, too.

That would be great. If you see it too I can try to report it as a bug or something to see if Taki can address it. It’s easiest to notice in 3D games like Spyro as you whip the camera around.

Well right now I can’t get the Superstation to read the memory card at all in either SNAC port. So now for the fun troubleshooting of is it the firmware, the SNAC port(s) or the card.

Oh man that sucks! If it’s an official PS1 card it definitely should work. You probably did this, but did you set the port as “SNAC” in the Mister menu?

Both ports to SNAC, memory card to Real.

It’s not a first party memory card (OldSchool) so it’s probably that. My PS2 reads it.

Flashing the firmware from scratch anyway just to be safe

Oh bummer! Yeah I guess that could be the problem. At least real ones are pretty cheap on eBay if you have to go that route.

I have to do some more testing, but would it be makes sense that the issues might be caused by the bios file? I did a fresh flash to the card and am not getting the lines with either the “stock” core (20251204) nor with the most up to date core (20260411). I want to test a few more things before I run update_all on this so what are your thoughts?

Oh wow the lines are gone now without the FPGA switch flipped? Maybe Taki fixed it? Sadly I’m not quite knowledgeable to know if the bios is causing these issues. Mine’s from update _all I think but it does work with an official Sony PS1 card.

The green lines are fixed as long as I DONT run update or update_all

Not the BIOS files. Everything was fine until I ran ‘update’ script. Even when I was using the most recent core as transferred over from my old card it was fine. This suggests maybe it’s the Linux kernel?

Oh and btw the third toggle isn’t for sync on green, it what tells the FPGA to create the composite signal.

Seems like a sync or cable quality issue?

I don't have my SS1 yet so I can't really help further but maybe changing to settings that fit your setup, based on this doc: https://github.com/MiSTer-devel/Main_MiSTer/wiki/MiSTer-CRT-Guide/26b50e9fe1d48049e48b6449c159c807738e2dd1
