Alright so, gonna use 68ohms since i got confirmation on another site..
Hopefully, someone will have the heart to help me out on 2 small questions remaining:
1- when using an homemade sd tool to read nand, where to i solder the crystal? i read that i need to solder the crystal to point C on official tools, but this one is homemade so i dont know what i should do with the crystal.
2- on the board of the console, i see i need to solder ground on 2 points (4 and 6), can i just bridge those 2 points together ?
