Ohhh...I see. So it needs the jumper wire for newer KS on the older boards.

Stupid question. I had a KS rom switcher kindly donated to me with an unknown KS on it. It didn't work with either of my r5 a500s. One of them has ks1.2 and the other has ks1.3. Neither has the jumper wire.

Would the wire do the trick? And is it 1->21 or 1->31?

is there any real reason to do the pin 1->31 bridge on the socket? why not do both 1->31 & 31->21 on the ROM?
