Does not work on SCPH-7000 & SCPH-7500 #78

I've tried both slot 1 and 2lot 2 images on 2 separate SCPH-7000 and one SCPH-7500 using different cards and both slot 1 and slot 2 images, nothing seams to work at all, I go straight to memory card menu. I have some 50 spare Japanese PS1s so I can keep on testing it. Edit: ps2 reports each card as unformatted so I suppose the files have been copied correctly, I've downloaded the file multiple times and used some older and newest versions of MC annihilator multiple times.

There's been a lot of "fake" memory cards sold recently, they have only 64 KB of memory instead of 128 KB. A few people have confirmed this, and what happens in this case is that the last 64 KB of the memcard image overwrite the first 64 KB, and the memory card appears empty.

You can open your memory card and check the markings on the IC inside, then a google search should reveal if it's a 64 KB or 128 KB memory card.
