Messiah 2 chip installation questions

[Spy_007z]

I am using the Messiah2_v3_Install(1.2c).pdf guide on my NTSC v3 machine. Here are my questions:

1- I have a non-gap bios, since the bios is on the top side of the mother board, I am just wondering is there a alt point for CLK and SCEx on the top side. So there I don't have to remove my mother board and solder on the other side.

2- The guide said that I should use 23 swg wire for 3.45v and Ground. Can I use 35/36 swg while as well? What would happen if other type of wires are used?

3- NTSC/PAL Color fix - I am confued on this part, do I shot the two point (Colour Fix Point & 3.3v)? What exactly I have to do for this? When a PAL game is played, will the game be off center still? If yes... then it is no use for the color fix and can I not install these wires?

TIA
