Matrix Infinity - which point is not needed

I have a v12 slimline pstwo which I wanted to play ps2 backup games and thats it. So which point I don't have to solder ?

I have try soldering all the point carefully (took me 5 hour to go through slowly) but no logo and won't play backup games only red screen. Now , I have desolder everything and I will once try again but this time only soldering the point needed to play ps2 backup games. any could help?

Thanks

You don't have to solder the F wire.

Have you flashed the chip, with a firmware that boots back-up ??
If not, that will give you RSOD

F is optional if you don't intend to use DVD-RW or DVD+RW discs.
