Bumping this out of sincere curiosity of the technology behind this and hoping the devs reply. I just recently bought Last Blade and Last Blade 2. DotEmu ported Last Blade 1 and was able to keep the menu and in-game bindings separate. Code Mystics ported Last Blade 2 and wasn't able to. Or chose not to? Which I don't see why, even if intended for fightstuck buttons.
Regardless, is the tech that hard to keep them separate?
