Moshi Monsters fix?

Hi, I'm currently getting a blank screen for both Moshi Monsters: Moshling Zoo and Moshi Monsters: Theme Park and I'm wondering if there is a fix released for either of these? I have an original r4 card.
Thanks,
Mark

For R4 original card revolution for DS / NDSL then use woodR4 firmware,http://filetrip.net/nds-downloads/flashcart-files/download-wood-r4-162-f32256.htmlUse Manuel download , Not auto.
