    Adding a few more codes I found a while back in case they were missed. I may have posted a few of these before.

    Power Stone NTSC J
    027FDC80 43700000

    Outtrigger NTSC U
    0283E284 43700000

    Dynamite Deka 2 NTSC J
    024FA878 43700000

    Capcom vs SNK NTSC U
    (main menu mis-aligned)
    023DCC60 43700000

    021F2C1C 43F00000

    Hi Sppiral! I'm testing this code and it looks like it has a strange bug with shadows and lighting effects. I think this "80EF0A8C" is the code responsible for this bug but I do not know how to fix it. It seems like the original code (1CF6888C) looks better than the modified one.
    Can you try to fix this?

    The PAL version of Sonic Code does not have Bugs with shadows, but the FOV of this one is actually much better.

    See that was what I meant when I requested a code for Under Defeat. I like how it looks with Trizeal though nice work!

    Sadly this is not possible with Under Defeat, there is nothing behind the black bars just a few more pixels rendered on both sides..

    Probably just simply enabled extended geometry in NullDC options would be my guess.

    @Anthony817 I need to learn...

    Lesson 1, never say never.

    It needs a bit of zoom in otherwise it'll look like the image above.
