The mobile (Android, iOS) version, made by Realtech VR, uses some structures. Those were reverse-engineered by Gh0stBlade.
struct AWBFile { uint32_t unknown0; uint32_t numFiles; uint32_t unknown1; uint32_t unknown2; AWBEntry entries[numFiles]; }
struct AWBEntry { uint32_t uncompressedSize; uint32_t compressedSize; uint32_t filePathLength; uint8_t filePath[filePathLength]; }
