| 0x08 || [[NPDRM#DRM Type|DRM | | 0x08 || [[NPDRM#DRM Type|DRM Type]] || 4 || uint32_t || For PS2 EDAT, PS3 OS requires it to be with activation (i.e. Local DRM). For [[PKG_files#Misc.2FNote|PS1 PKG]], PS3 System Software version 4.00 introduced some changes for installing them with regard to the EDAT DRM type. | ||

| 0x40 || Digest || 0x10 || uint8[0x10] || QA digest. It seems to be a SHA-1 hash of the non-finalized file (debug SELF/SPRX created with make_fself_npdrm) or of the original EDAT data. Original data are unknown until the whole file is read, so it cannot be used as a check, however it can be used as watermark or zeroed on forged file. | | 0x40 || Digest || 0x10 || uint8[0x10] || QA digest.
