Certain in-game keyboard commands don't respond in Atari Computer Core

I realize this is probably on the bottom of the heap of support, but… I’ve have the Atari 5200/800 core set up to use with the Atari 8-bit computer and games. Everything’s working perfectly, except certain games that require particular keyboard commands. For example, one game requires the P command to pick up items, but there’s no response. I toggled Game Focus, and it makes no differences…also, in the core’s input, I switched from Atari Joystick to keyboard with no luck as well.

Then I tried another game…an old 8-bit RPG called Alternate Reality where practically none of the keyboard command worked, yet, I threw up some random text adventure, and all the keys work. This is all within the same core. I even setup my old Xpadder program and assigned a keystroke to the gamepad, and no luck there either. Any ideas? I know these worked on this emulator years back before RA. Thanks
