Early on, I must have tested a bad rom. 1942, my sample test, works if I switch to the .225 standalone and launched through retroarch. I only converged on 1942.zip because I wanted to post and make sure I was comparing apples to apples. That said, whatever is built into retroarch and the .176 (exact) edition standalone do not work. So whomever made the rom set, while I bless them, was probably not spot on with the compatibility.
