Hi All... My guess is that this may likely be a ROM issue; though, I want to check as I can't find the specific issue through my searches so far.
Environment:
PC: Windows 10 w/all latest patches
External Drive: LaunchBox w/thousands of games and associated emulators
Gamepad: X-Arcade Arcade2TV
Set to xinput mode (4)
Configured using xmapper - all buttons tested & working
We've only started with the MAME games so far and tested Asteroids, Marble Madness, Galaga, Ms. Pacman, Millipede, and Marvel vs Capcom. We did start up a few other games but couldn't get beyond the start menu.
Issue: In Galaga and Millipede - none of the buttons fire which means we can't play the games.
Any thoughts?
