ShadowKnight mentioned required conversion from NTSC to PAL here .
When is this needed, I have an NTSC v5, I'm pulling out my messiah 2 v1.30 to put in a DUO, should I bother with the above procedure?
Also, is this related to the NTSC color fix point? I remember reading up about the color fix point for DUO somewhere in the forum but I can't seem to find it anymore. Is it the same as the messiah 2 as in charlie_ps2's guide? Thanks.
