Sorry, not sure I understand. Are you saying you are releasing a version of berryboot for the banana pi yourselves?
I've asked max at berryboot and this is what his reply was:
Banana Pi will probably work with the Cubieboard 2 image if you overwrite the script.bin file on the SD card with one borrowed from a Banana Pi image.
If they use different RAM chips than the Cubie, you also need a different u-boot SPL.
To find the script.bin file do the following:
Borrow it from any of the operating systems images the vendor provides. First (FAT) partition on the SD card.
If you are stuck with Windows:
1) Go to download page on vendors' website. E.g. for the Cubietruck that would be: http://cubieboard.org/download/
2) Download any of their own operating system images, e.g. Ubuntu or Android for Cubietruck
3) Write the image file to SD card with a program like Win32diskimager
4) Eject SD card, and reinsert it, so that Windows sees the files on it.
5) Copy script.bin from the SD card to a folder on your computer.
6) Now write the Berryboot Cubieboard 2 image to SD card with a program like Win32diskimager
7) Eject SD card, and reinsert it, so that Windows sees the files on it.
8) Copy the script.bin file you saved to a folder on your computer to the SD card, overwrite the one provided by Berryboot (which is for the Cubieboard 2)
The u-boot SPL file must be recompiled from source. I'm not sure what the steps are for that yet. Perhaps you can shed some light on what this means.
It would be amazing if berryboot worked on the banana pi. Just think of the possibilities of easily bringing in new users to the banana pi. Anyone familiar with the raspberry pi (and who isn't!) can take their favourite raspberry pi O/S and run it through berryboot on the banana pi. Looks like a win win to me.
Please let me know what your thoughts are on using berryboot on the banana pi. If I can find a distributor who will ship to Canada I will buy a banana pi and work with you on getting this working.
