EatingInRetro.Hello
I followed some of the settings posts for the N64 that I found in this forum and things look pretty ok but I’ve noticed while looking at any of the games it looks like the colors are pulse/wavy or refresh in areas unevenly. Is this something that is just normal or should is there something I can do to fix this?
I have seen this type of issue due to many reasons. Your first step should be in narrowing down the cause.
Questions:
1) Does this issue happen on a different N64 console?
2) Does this issue happen with a different power supply?
* Check the N64 console and OSSC if possible
3) Does this issue happen with different cables?
* Check the N64 console and OSSC if possible
4) If using a flash cart like an everdrive, does this issue happen using the original cart?
5) Is your OSSC running the latest firmware?
* If not, try upgrading.
* If so, try downgrading.
6) Does this issue happen on a different TV?
7) What are your current OSSC settings (sampling, sync, and other timing options) ?
Screen captures, your affected games, and your affected consoles would help.
Thank you for giving me some direction on what to check. As for settings I am using:
H. Samplerate – 387
H. synclen – 22
H. backporch – 34
H. active – 320
Sampling Phase – 22 deg
on version 0.82a
I only have an unmodded N64 which I don’t think will help? I could use the power supply from that and test that part.
I don’t have another scart cable, would it be worth buying another and testing? I can use a different hdmi cable.
I don’t have any carts to test with at the moment.
I tested it on my TV and it also showed on OBS preview.
For capturing I will have to capture a short video.
I’ll update once I am able to test all these steps.
Here is a video of the issue. You can really see it during the white transitions and in the blue sky while Princess Peach is talking.
Unfortunately your video has been taken down. You may want to upload to google drive.
Not sure what happened to the video but once I signed back in everything was good. Could this be from the scart cable?
Do you have Tim Worthington’s board installed in your N64? It is hard to see the flickering due to the compression but I think I had the same issue (it was especially noticeable at the grass in front of the castle). I’ve built a clone of Tim’s board and I had this kind of noise until I’ve installed a 3.3V regulator instead of the direct 3.3V rail. I’ve read it can be a problem for the official release as well.
Yes that’s the board I have installed. Can you direct me on how I can install this fix? I do know how to solder.
ok I found the 3.3v Voltage Regulator that says it’s an upgrade for my mod. Any good videos with some basic idea on where this should go?
I don’t know. I’ve just added the 3.3V on the board, scraped off the solder mask and soldered it. It looks ugly but it works.
I’ve just found this video, it should have everything on how to do it: https://www.youtube.com/watch?v=NxGIhH4mSoI
Thank you
