Go by RC / RC de Go booting ?

[Sp33dFr34k]

So basically, still no definitive marker? I wonder if one exists...

I wonder if the difference is on the mobo at all, perhaps it's a difference in the Gnet daughterboard

I tried different daughter boards and the issue stayed with the mobo.

I've created an album here with pictures of my PCBs, the image description says which ones boot the game and which one does not:

if anyone else has similar images they can take and send to me (as high res as you can) both booting and non-booting boards I can add them to the album.
