Pokemon soul silver: patched but still freezing

So it worked perfectly till I beat the third gym.
now my game is freezing/showing black screen:
after saving
after leaving/entering buildings
after leaving bagI used dslazy patch( I also tried the patch with a green leaf as icon but that didn't work either)
I use a M3 ds real with the newest firmware for it

Keep it to the sticky Topic on this issue.
