PS2 Green tinted image with OSSC

[Maka8295]

Hi, my PS2 is producing a green tinted image with my OSSC. I’ve tried multiple TVs different PS2s and have set the PS2 to RGB in the settings menu, i’ve also tried fiddling around with just about every setting I can find on the OSSC and can’t seem to fix it. My SFC displays with great colours but has a strange interference problem which i’ll get into shortly. Because the SFC colours display properly, the problem occurs on multiple TVs/PS2s i’m afraid it may be the PS2 cables at fault, which I ordered for a rather hefty price at retro-access…

For the SFC problem, I have two theories, its a problem with my aftermarket power supply, or this problem here https://videogameperfection.com/forums/topic/nes-snes-240p-audio-video-stability-issues-read-before-posting/

Any help at all would be greatly appreciated 🙂 I’m pretty keen to play these games again…

If you’re matching RGB on the PS2 side to RGB on the OSSC side, then I’d say that looks like the wire for red is broken/disconnected, and a new cable should clear that up.

Board revisions APU-01 and RGB-01 of the Super Nintendo have those diagonal lines in the image. Check your serial number at https://docs.google.com/spreadsheets/d/1HYLy_TTDop_FzuX6qnxuQI43upg4raXfno582taO744/pubhtml

If you don’t have one of those revisions then it is caused by your RGB cable.

Thanks for the responses! It seems the SFC is at fault for that problem, and i’ve contacted retro-access about the PS2 issue. Thanks!

Hmm actually it seems my SFC is an RGB-02 model (serial number with SM117****) does this mean it is the cable at fault?

[paulb_nl]

Depending on what cable you are using the console and cable could both be at fault. APU-01 is a later revision than RGB-02 so I think it still has the same issue. Though serial SM117 is closer to APU-01(SM119) on that list.

The GPM and 1-CHIP are the best revisions with 1-CHIP being the sharpest.

When I changed from ps2 7x to a ps2 9x it worked perfectly. Same cable, same OSSC, same setup. I think it could be an incompability between my ossc unit and ps2 7x.

No such incompatibility exists that we know of (after all these years we would have surely discovered it). My guess is a fault with the PS2 console itself.

I remember experiencing an issue with the OSSC Classic on my Sony TV (an old 2007 model) where the Cr and Cb samples got mixed up in its internal processing under some circumstances, which was fixable by offsetting H.backporch by 1. It was some time ago though, so I no longer remember the exact details.

It could be a similar issue, the display getting confused and swizzling the components around because of the input signal being non-standard.
