Re: Building Linux kernel

Hi! Is there any limitations to building and using a kernel based on the "socfpga-4.19-MiSTer" branch? Is "socfpga-4.5" still the "official" branch?

EDIT: Never mind, 4.19 is the official branch it seems, didn't read the thread properly enough.

Re: SDRAM board

Got the parts and soldered a 128MB SDRAM card. I used Sorgeligs capacitor configuration (shown below) and it seems to work fine (stable @150MHz).

DIY MD/SMS/Atari/C= to USB adapter

I designed a simple to build Mega Drive, Genesis, Master System, Atari, C= controller adapter around the Arduino Pro Micro. The Arduino Pro Micro has very low latency when configured as a USB gamepad so it's well suited for these things. 3 and 6-button Mega Drive/Genesis gamepads are supported, also...

You can't expect to get error free behaviour @167MHz, try 150MHz and below.

That seems cheap :)

According to the MiST wiki, those cables won't work out of the box, but can be modded, at least for video.

I don't think directvideo is the issue, are you sure Mister.ini is in the root of the SD card? (Previously Mister.ini should reside in the config folder).

Re: Original analog video without I/O board? Possible!

Damn, I assumed that my adapters had the AG620x but they both have the CM6616, even being of this type (one with audio port), buyers beware:

I ordered a UGreen adapter now that will hopefully work.

Maybe this one could work? Haven't tested it myself though.

Nice, good work! Personally, I would love to have this on my MISTer even if it's not purely fpga, would make my MISTer even more versatile. If it doesn't end up in the official repo, please make it available somewhere else, thanks!

By the way, how do you connect the toslink cable to the adapter? You have some kind of plastic ring around the perfboard, can you give some more details, thanks! :)

Re: analog audio

I strongly recommend buying a small DAC which outperforms the analog output on the mister. Many people use this one with the mister, including me: https://www.ebay.com/itm/Optical-Coaxial-Toslink-Digital-to-Analog-Audio-Converter-Adapter-RCA-L-R-3-5m/202179203058?hash=item2f12d1cff2%3Ag%3A2TIAAOSw3...

Nice - but you should add Pin 12/14 as GND - it's maybe then more clear for some people.

You're right, I updated the schematic.
