You're welcome! I will try to assemble my board over the weekend. Got all the components now, I think.
Mine have arrived, as well.
Thanks for the small group-buy, root42!
Awesome, too bad there was little native SID support. I would love Planet X3 support for the SID chip.
There's also the custom SSI driver for John Miles Audio Interface Library which can work well in some games.
I made a video of Legend of Kyrandia with the custom AIL driver for the SSI some time ago:

Don't forget to check in advance whether you need Fagear's compatibility mod for fast ISA buses.
It would still be possible after assembly, but the square pad simplifying it would then be hidden below a chip.

I'd like to add support to Planet X3 at some point, but wanting to have it does not magically double my spare time, so don't hold your breath for it.

You will have to walk me through this on the stream. 😉 I have no idea what Fagear proposed! I will be running it on a 25 MHz 386.
A 25 MHz 386 should technically be slow enough. There's a note in the schematic describing the mod, in case you want to do it, anyway.
In any case, I suggest that you print out both, the schematic and the component diagram.
The schematic because it contains helpful notes and the component diagram because there are no component designators or component values on the silk screen.
i will watch you on sunday and assemble the pcb right after you 😀 maybe it saves me some time

Erm... Looks like you're populating everything for the STM32 configuration, including the resistors that set the regulator to 3.3V.
And no, JP2 would short out the regulator. JP2 is for the configuration without regulator.
It's also funny to watch you try to solder 0603 SMD parts without holding them in place.
The jumpers set joystick sensitivity, IO port and joystick en-/disable, respectively.
The individual one en-/disables the joystick.
Congratulations on getting it working!
Let's see when I will find the time to adapt the STM32 emulation core for the optional on-board STM32.
That should result in an even cheaper solution than a fully assembled card plus SwinSID.
Great Job in reversing / cloning it - and awesome to hear it work!

Well, as indicated in the first post, most of the reverse engineering had long been done by others.
CodeKiller's annotated board photos from 2012 where particularly useful. The optional mod for fast ISA buses is by Fagear.
I merely re-reverse-engineered everything from there and added the still untested option to use readily available new components rather than vintage parts.
Glad it worked out in the end! 😁 Now waiting for my 558s. I also shared a Mouser project, using the blank bracket and the SSOP-14 NE556s. Should be complete, apart from the STM32 (but including it's supporting resistors/caps):

Big thanks!

These rearrangements also allowed me to further minimize the visible differences.
There's still four additional traces on the back side of the board, but they are now much shorter and do not shift other traces anymore.
Could you also make a fork for a card that fits the Keystone DB15 bracket? That way people could opt for a not-so-authentic look with an almost readymade bracket (apart from the RCA hole). Otherwise I might just make a fork and try to do it myself. Have never done anything in Kicad. 😉

Nope. Still not interested. I'd rather try to finish the project before I expand it further. However, feel free to have a go at it!
Apropos connector: Are you sure that the DA15 socket you installed has the correct dimensions? It appears to stick out a bit, while at least the plastic part should be flush with the edge of the board.
