I seen some video where they mod PS2 Slim with a SD directly wanted to do the same thing with Fat PS2 but if the memory slot 2 still doesnt function as normal then there is no benfit of doing it beside saving a memory card as a donor.
If I attach the mod to the memory card pin on the PS2 instead of the memory card, can i still use memory card 2 slot for saving and have MX4SIO active at the same time?
