==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.  These files are probably not compatible with standard 360 file access calls (Xenia logs show no attempts at accessing any files beyond the BNAs they are stored in).

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. These files are probably not compatible with standard 360 file access calls (Xenia logs show no attempts at accessing any files beyond the BNAs they are stored in).

File Formats Under Research

BXR Files (Bandai? Xbox? Resources)

BXR Format
Entry Size Notes
Magic Header 0x4 "BXR0"
Unknown Data? Varies with number of resources cataloged Bulk of research to be done here
Resource Listing Varies with number of resources cataloged Plaintext, separated with 0x00

AIX Files (Audio? I???? X????)

Criware proprietary audio format. Seems to be an archive?

AIX Files
Entry Size Notes
Magic Header 0x4 "AIXF"
Metadata Header? 0x43? Some kind of metadata for the file as a whole?
Subfiles Metadata Table 0x17B3 Table of data for subfiles. Each entry 0x10 bytes. If less than 0x17B files, remaining entries are zero filled.
Magic Footer 0x6 "(c)CRI"
Subfile Data Varies
Zero Filled Footer? ???? Unsure if part of final subfile or AIX
