So it happened just like then? No downsides? Pretty awesome if that's the case.

Great!

Any changes needed to the pinout info on the wiki or is it the same?

Saw this info in the release notes, so just want to make sure:
"PWM audio is available on GPIO pins 12/13 for this model."

The pinout table in the wiki does not mention GPIO pin 13, but GPIO pin 12 is used for something called 'I²S BCLK' (been there since before this latest release)

Sorry if it's a dumb question, just want to make sure I don't connect wrong(don't have an IO board) :)

I use i2s as audio out and configured my GPIO like in the wiki - so 12 is connected to D11/MOSI (i.e. I²S BCLK). I guess i2s and PWM audio are mutually exclusive - so then one could reuse 12 and 13 for this. But that would be a bit strange, as there are so many GPIO Pins available. I do not know :( :? :)

First, don't confuse GPIO pins with physical pins. GPIO 12/13 are on physical pins 32/33 (see https://pinout.xyz).

Second, PWM audio is ... just that. PWM audio. This is irrelevant for MiSTer use, which uses I²S. This changelog note is for weird people who want to reconstruct the missing "headphone jack" PWM audio circuit you normally find on the larger Pi models, which is, as we all know, poor quality for this use case.

TL;DR - ignore that changelog note, it doesn't apply to you. The MiSTer connection pinout on the wiki page is still correct.

Have fun! 8-)

Do you think its possible to PXE-boot the PI from the DE-10 nano?
