Hey @megari I found out Amazon sells USBASP programmers so I just got one next day lol.
I went through the process using a combination of the steps from the wiki and the video, and I was able to get it updated.

Results: The 480i from dreamcast s-video looks fixed for me, Great job! I did some AB testing by switching between my CRT’s native s-video port, and component through the koryuu s-video. Both pictures looked very nearly identical. The only thing I saw was the colors might be slightly brighter going through the koryuu. This might be a TV setting for all I know.

As for 240p test… I was using a genesis model 1 with sonic 1 to test the composite transparency trick on the waterfalls. My main goal in using the koryuu is to sidestep my trinitron’s bad dot crawl issue with composite signals. This generally works, but the koryuu introduces some other issues. For example the dimensions of the overscan changes slightly, and I am able to see the edges of the left side of the picture when using the Koryuu vs the native composite input. Also, the quality of the color change is much more significant. Colors seem to be blown out and maybe slightly hue shifted. I wish I could give more specifics than that. It is difficult to screenshot the subtle differences on the CRT picture. The last issue is there is a steady flicker to the image that I do not see on native composite, or s-video dreamcast into the koryuu. I wonder if this could be the age of the genesis not playing well with the koryuu. I have a much younger Genesis 3 that I will experiment with when I get the chance.

Thanks for the help.

Thanks for asking! Actually I’m still waiting on that special USB programmer. The first one I ordered was lost in the mail. When it finally arrived literally a month later, it was smashed to pieces. I’ve ordered a replacement and tracking says it just cleared customs. I realize I coulda just gone to a hardware store at this point but I got busy with a move. I’ll reply in this thread when I get it all working. Thanks again!

Thanks I’ll try to make sense of this this weekend.

Came to request this feature, and found this thread!

There’s something similar on the Koryuu, though I know its experimental, it’s the right idea of what I’d like to see. Definitely would love to see this feature with multiple steps of blur strength. I sometimes play with composite piped in through the Koryuu just to get this effect with the natural blurring of composite signals. I find composite + Koryuu + OSSC 5x with thin scanlines is pretty faithful to the original experience on a CRT. However, it would be better to recreate this with a cleaner signal of component/RGB.

Ah. I am on the latest firmware, but for what its worth I hooked it up to my PC monitor and it didn’t have issue with 1080p. I’m glad I was able to get it working on my TV, though.

Hah! Nope! DVI mode looks beautiful! The other mode, HDMI (YCbCr444) also works, but it looks a little washed out compared to DVI. Thanks so much!!

Interesting! I was able to find some off screen footage of OSSC 480i. This gives me something to consider. I’ve got a consumer CRT and I’d prefer to use that, but getting a working set that doesn’t have something about the picture failing is getting harder and harder.
