Medarot DS rom on Acekard 2i Help

I downloaded the medarot ds rom and the patch. I have a acekard 2i and i placed the two files seperatley inside the acekard, but it just gives me a white screen. When I hold the A button while loading, it still doesn't work. I also got a patched rom that said it worked on the acekard with a aio folder, but it still had the white screen? Can anyone help me out??

Use AKAIO 1.7, and a clean rom. Do not use patched roms with AKAIO.

how do i use AKAIO 1.7? can you teach me? do i download it?
