I am sorry. Suggested by you, I find DB9_MULTI_0802_2 on db9.c now. I
will try to hack db9.c. DPP compatible JOY-DB9.C patch previously exists.
(http://www.self-core.org/~kaoru-k/pub/joy_db9_dpp_saturn_2.2.17.patch)
Below patch is preliminaly support for ninth button on db9.c compatible
interface. I have not tested if it works or not. (I have no interface
nor knowledge of 0x37a command register.)

But using gamecon.c might be the easiest way to support more (12 pads
with two multitap on each connector, in maximum) pads, although satun
pad can not live with other pads in my gamecon.c patch.
