GTA CW - Multi-Card Problem

Ok I have an R4 with 1.18 firmware. I got GTA CW to work fine but I can't use the multi-card play or the Wi-Fi option. If anyone has any ideas or ways to fix this problem I'd really be grateful.EDIT: Nevermind I got it working.

can you tell how? im still searching for the answer. does it involve ysmenu or something, or did you found a crack?

No. Just the regular ARM patch.
