Arm7 fix help.

I have a ds-x and have been recently been trying to get DK Jungle Climber and Drawn to life to work. I have tryed Arm7 and it doesn't work for me. I hit y and nothing happens, so if I could get an extremely detailed description on how to fix it or a link to a pre patched version of these two games that would be great.

the DS-Xtreme shouldn't need to use the arm7 fix as far as I know.Just make sure you have the latest firmware from: http://www.linfoxdomain.com/nintendo/ds/

I have the latest firmware... It says I should remove the cart and has a black screen when I try to run it.

i cant play club penguin it says
'save data could not be accessed. please turn the power off and reinsert the DS card.'
and every one says get the arm7 i dont know were to get it from or how to applie it
