help pw2 patch.

I need help with the pokemon white 2 patch. Everytime i try to open the patch it says error and doesnt let me open it.
I was wondering if anyone could patch it for me and other people experiencing this problem and upload a link on this tread with the game already patched.thanks ahead. note i dont know if this is the correct thread but no other thread has been able to help me =/ thanks ahead .

if you are talking about AP patch, download DS-rom tool, open your game with it, export it applying the ap patch

Do you get an error if you do as it says here: https://www.romulation.org/tutorials/using-xdelta-to-patch-roms/ ?

I have downloaded the white 2 patched rom but it stuck at driftveil world tournament... I have a supercard dstwo.
Can somebody fix it please :-) ?

ive got the game to work with experience patch good now but in the second town after talking to a bald headed man the screen goes black anyone knows what to do please help game is awesome so far.
