The problem there, would be that the Arcade card doesn't include the possibility for a 2nd bg layer, nor does it include more colors(SGC has somewhere around 4000 colors), & I think there's a few other things that I assume would require a cpu in the Arcade card to make SGX game work, it just ain't happening. A brand new card would be more doable, rather then taking an Arcade card apart & adding stuff to it.
