Summary	06151: MAME fails to accept input from XBCD-supported joysticks with DirectInput 8
Description	The input module detects the joystick, but it does not react in any way to joystick input when attempting to bind the buttons. It appears to be driver/device-specific, as the PS3-compatible joystick I have works just fine with official 171 build.
Steps To Reproduce
Additional Information	Attached is the OSD debug log for all of those (Windows 7 64-bit is used).

No.12457 hap Developer Mar 11, 2016, 10:24 edited on: Mar 14, 2016, 01:19	I assume the issue I'm seeing is related to this. On Windows 10 64bit, using an Xbox One gamepad. If I focus to another window, then back to MAME and open the OSD menu(TAB key), the cursor will move down-right by itself or get stuck. It appears MAME thinks the left analog stick is pointing to down-right. MAMEdev Kale confirmed this problem too, also Xbox One pad. edit I think this specific issue was fixed in 679574e96589fb62c12c4614bf8a5c96c97c9fdf
No.12463 vvv Tester Mar 21, 2016, 07:08	So, I have good news and bad news. The good news is that I had observed the bug hap is describing (it was present even with DirectInput 7), and I cannot reproduce it in the newer build of mame (git revision 3afd99022), so it's probably fixed. The bad news is that my XBCD-driven joystick still does not work with DirectInput 8.
No.12676 Quench Developer May 20, 2016, 17:10	I've just posted a fix (git: 7d7d36622304ebb9ff83c4541bd69a642a1d186f) which may resolve this. If you get the chance, try building the latest source with DirectInput8 (or wait for the next version release which is soon), and let us know. Thanks.
No.12751 vvv Tester Jun 9, 2016, 23:35	I've tested it. It works (without any makefile modification) in the 7d7d366, and does not work in parent revision. It also works in the released 174 binaries. Thank you for fixing it!
