Xbox 360 Wired Not Working In-Game

[ridiculousmoe]

Hey folks,
first post, thanks for your time!

I'm using wired USB XB360 controllers,
Tried on both Mega Man Anniversary Collection and Metal Gear Twin Snakes

Seems like we got everything set up properly for Gamecube Controller config, Port 1 -> Standard Controller, all of the Xinput mapping went smoothly and recognized each input. background input selected.

But with the games running, the ABXY, etc buttons aren't responding on any build version that I've tried.

I've tried the latest dev. 7082, 5.0 stable, 4.0 stable, and 3.5... What I did learn is the thumb sticks appear to be working in the menus, as well as the right thumbstick analog is doing that zoom thing during the MGS initial cutscene..


Any ideas? Thanks again
-Jake

I was able to get the same controllers and dumps to run fine in 4k on both of my other systems with version 5.0. one with an FX8320 and the other has a i52500k. so it's something with this rig, maybe a driver?

This one is a
i5-4670k
GTX 770 2gb
8gb
Gigabyte z87
