My question is does anybody have a pin out or wiring diagram for the DB9 port SNAC port, DB9 to USB adapter or know what pins I would have to solder the USB port wires to make this work?

Here is a thread with the pin mapping. viewtopic.php?t=5075

Very cool project! It's pretty useful for folks using modern displays as well, any plans to add Shadowmask and Adaptive Scanline support?

Sounds like you need to build and configure the MT32pi SD card.

How can i contribute if i have new ones i created myself?

The best way is to submit a pull request to the repo, there are a couple of us who can approve. If you're unfamiliar with git, post them here and one of us can add them.

Does someone know how often the gifs are updated?

It's sporadic and infrequent You can see the repo's commit history here: https://github.com/h3llb3nt/marquee_gifs/commits/main

I usually try to whip up new static GIFs as new cores are released. h3llb3nt is the one who creates the excellent animated GIFs

Overwrite is to prevent any custom GIFs added on the MiSTer SD aren't overwritten by the GIFs in the repo.

No, I think it's a bug. I changed folder names at some point and probably missed something.

I still need local storage to unpack them before transferring them to the matrix, a deletion after the matrix was updated could be added.

Sounds like you found a bug in the Matrix SD update part of the script. I've logged the issue and will take a look when I have a chance.

You are correct in your understanding of the switches. The path is for the local storage of GIFs on your MiSTer SD Card, I would leave it but you can adjust it to whatever you'd like.

I connected as below, but I don't know if it's right

CS to pin 33 on the trinity
SCK to SCL on the trinity
MOSI to pin 32 on the trinity
MISO to SDA on the trinity
VCC to 3v3 on the trinity
GND to GND

Which one is it? This here above or like on your images?

Assuming you're using the Trinity board, you can source it anywhere labeled '5V'.

Ok so only display the name of core, no possibility to display rom name on led..

MiSTer doesn't currently provide the ROM a Core has loaded so there is nothing for us to use. If there was it would probably be just a small tweak to the linux service code.

One question..
This project works only with Arcade gifs? Or is it possible display name of games on console? If yes which is the correct naming convention? I tried for example to rename Genesis_Batman.gif for the game Batman but it doesn't work.
Thanks you

It works with MiSTer core/setname and Retropie system name.

Finally I can see the size of memory!
Card reader needed 5v and not 3.3v

Thanks, I'll clarify that the module in the docs is 3V.

I've expanded my assembly documentation on GitHub to better explain the wiring.

Hard to tell as you used a different module than I did. In the pictures, it looks like you're sourcing power for somewhere besides the 3V3 pin, also your SD card module looks to have a regulator on it. Are you sourcing and supplying the correct voltage for your SD card module?

Those are just warnings and can be ignored. My guess is that it's your SD card wiring.

I have documentation and photos in the GitHub repo: https://github.com/kconger/MiSTer_web2rgbmatrix

Please let me know if anything isn't clear and I will try to update them to account for it.

In case anyone is interested GameBoy printer emulators like these work using the GBLink cable SNAC adapter. You will need to make sure link detection is off as the SNAC adapter doesn't have the VDD line connected.

I've released a new version that centers the GIF marquee if it's smaller than the display width.

For USB programming try reducing your baud rate, 921600 was not stable for me.

For OTA are you using my web interface?

That doesn't look like my code, it looks like you downloaded GitHub html.
