Question about reading and writing data with sd card

[kof888]

After testing, direct nop instruction has the same effect

mov.w r3, @r7 ! FFE80008 = 30

Then, we only need to re-initialize the register FFE80008 to 0 before issuing the cmd command to read the SD card data.

In this way, there is no need to modify the image. This method is effective in testing and should improve the tolerance of the SD card to other games.
