Cyclods flashcart pokemon platinum help

Hello if this post is against the rules please say so.I am using an cyclo ds flashcart running with the latest firmware (v 1.56 B1) and I have a problem accessing the pokemon platinum rom (3541- by Xenophobia) . A few weeks ago the rom worked fine, but now when i select the rom from the ds menu it loads then it pauses on a white screen. I have tried the arm7fix and it still doesn't work (unless i did it wrong). Can anyone help me out?

Use the new American one :P. If not, dl the ROM again, ARM7 patch it correctly, and update your Cyclo to the newest non beta firmware.

Ok will try that, but will HG/SS still work with the non-beta one?

You'll still need to have the patched ROM yes.
