Wrong colors on CRT with s-video transcoder #15
Comments
Here's a capture from the analog IO board to a retrotink 5x Pro using YPbPr. Looks normal to me for analog video in general. Maybe @MikeS11 would know something about what is going on, he's dove really deep in YC lately. |
This has more to do with the external AD7XX(or other?) encoders inability to match the core to the reference NTSC frequency. There are some arcade cores like arkanoid that have the same issue. As the core matures, timing improvements may help but at the moment its not really a core issue. If you really need Y/C you can try the YC test build. |
Thank you @birdybro and @MikeS11 Yes, I was suspecting this, as I have the same issues with some arcade games on MiSTer (Wonder Boy) and emulators with the very same encoder. I have the following workaround: I send the analog signal through an OSSC, configured at 1x, and the through the s-video encoder, and it works OK. Probably, the OSSC is "standardizing" the frequency. @MikeS11 I didn't know about the YC builds ( https://github.com/MikeS11/MiSTerFPGA_YC_Encoder/tree/main/YC%20Builds ). I need to find a cable to try it. Thank you!!! |
This issue is not related to the core. Ticket can be closed |

Thank you, but it doesn't. I have the same problem with this version. |

Again.. Thank you, but same colors :( In this picture you can see also more clearly a vertical bar on the left side of the screen that has been there since the first release. |
Also experiencing the same incorrect colors on the Retrocastle analog board when outputting to a CRT via svideo. Just providing another data point. Thanks again for the great work!!!! |
Also an issue for me -- this is the only core where I experience this behavior. (And +1 to SplashAF -- thank you for the hard work!) EDIT: It's perhaps worth noting that I have the issue with the Antonio Villena S-video converter. So it's not just happening for folks with the wakabavideo converter. |
Thank you for this core!!
I got wrong colors when using a CRT @15khz, I tried both the analog IO board and direct video. Then I use a transcoder to s-video (wakabavideo).
All other cores work great with this transcoder (except for Wonder Boy arcade core that has the same behavior).
