Scratchpad Filesystem

BNA archives store files in folders that do not exist on the ROM.

For example, /root/bg3d/b3d_audition_a1_ill_wat.bna exctracts a file into the folder /root/bg3d/audition_a1/ but does not create this folder itself. /root/bg3d/audition_a1.bna does create this folder, indicating something in memory is keeping track of files.
