Batman The Video Game

I put together tracks from the actual movie that wanted to swap in. I downloaded some of the necessary files. I followed the arcade TV guide and am stuck on the hack and build rom portion. I don't understand the part in bold it just says folders. The others have a specific name. Also can't find those batches mentioned in bold.  I made myself an unofficial soundpack as well.

This may vary between patch repositories, but I will update older releases to use the same structure for convenience.



Think this may be over my head. But I would love to see this happen, either by me figuring it out or someone creating a patch for it. I believe it uses a custom Sunsoft sound driver so I am not sure if it is possible. Thanks.
