Hello,
I was told to come here to get help working on getting the config.h mapped for the new xd75 clone from Massdrop. Massdrop along with the organizer Xik have not responded to any questions nor (from what i understand) support tickets on this board. The board looks like an XD75 from KBP, however when you flash the default XD75 firmware, no keys work. I have gotten the map below figured out using the default Atomic firmware, obviously the keys are not in the correct places, but this is at least giving some insight on what pins are being used. Laying this out this way was an idea of @rumlyne and it makes sense to me, but idk this might not actually be helpful.
The point of the post is to get some help on how to get this figured out, since it seems the maker/organizer isn't going to give us the default firmware or point us in the right direction, i think that we have the means to figure this out. I'm having a hard time finding guides on how to do this from scratch, and since the chip is soldered directly to the board i don't think there's away for me to figure out the pins just by looking at it. So here's what i have after flashing the Atomic Default firmware in qmk

Hopefully we can get to the bottom of this, any pointers on the process would be appreciated. I'm thinking the next steps are going to be changing the pins out in the row/col that aren't working at all.
