OK! Let me explain. At the moment I play all my original Sega Saturn games on the Polymega where i am able to apply various hacks and patches to games in my current library. Currently I have over 400 original titles that i own physically. Unfortunately I am unable to patch my Japanese copy of Doom for the Saturn via the Polymega interface. Most of my patches work. For example, Doom for the 32x I was able to apply the patch successfully.
