Help with cube
 

I am running the alltel rom with the cube that come with the rom.
I was able to change the names and paths/ext for the programs I want to
run using the cube configuration tool. The issue is I am trying to change the .brn images and have not been able to figure out how.

Question 1: Can I do it with this cube or do I need to change to another cube like macflo, icube etc...

Question 2: I am not to fimiliar with image conversion or whatever it's called
do I need somekind of converter or do I just change the ext of the image file (which isn't realy working for me)

Question 3: Is there a thread already discussing this or with .brn images already uploaded can someone please point me to it.

Thanks
