Messiah2 Pro install test question

SCHP 3001

I read the instructions for the v7. It says to "test" the basic fuction of the chip, just soder GRN, 3.45v, RESET, SCEx, and CLK.
Now none of the other model instructions have this, but will this test work on other models? Or do i need any other wires sodered. Like the 3.45v to video bypass done also?

And if possable, can it be left this way. So as to just play back-up PSone games. Say for someone without a DVD writer yet.
