    6 VME 6 VME The VME (Virtual Mobile Engine) is a reconfigurable processor to decode audio/video. in 2002, Sony developed the Virtual Mobile Engine? as a method for achieving significant power reductions and miniaturization in LSIs for audio/visual products. This circuit technology, which can reduce power consumption by approximately 1/4 over conventional general-purpose digital signal processors (DSP), was adopted for use in the CXR704060 LSI used in the Network Walkman "NW-MS70D".

    So code signatures are done by the developer, while encryption is done by Sony. The trust can still be verified by checking the signed game certificate, seeing that it belongs to SCE_CA0x, and then seeing /that/ belongs to Verisign, which is the root trust node.

    26.2 PRX (PSP Relocation eXecutable?) Sony’s PRX (PSP Relocation eXecutable?) format is a relocation executable based on the standard ELF format. It is distinguised from a normal ELF file by having customised Program Headers, Non-standard MIPS relocation sections and a unique ELF type.

  • Page 135: Unique Elf Type

    26 FILE FORMATS 26.2.3 Unique ELF type PRX files report the value 0xFFA0 as their type in the header instead of 0x0002 which is usual for normal MIPS ELF files. 26.3 PBP A PBP file collects the files needed for a game executable from a MemoryStick into a single file, for easier transfer. The files are simply concatenated with a small index at the start.
  • Page 136 26 FILE FORMATS The last part of the file is the value table, again at an offset indicated in the file header. Since value data is required to be aligned, zero padding may exist between the key table and the value table. The offset in the file header will indicate the true start of the value table though.

    26.7 PMF (PSMF) PSMF, or PlayStation Movie Format, is a proprietary movie format created by Sony for the PSP. PSMF videos can be as small as 64x64 pixels, and have a framerate of 29.97fps. The video codec used is H.264, also known as MPEG-4 Part 10 AVC. The audio codec is the Sony proprietary ATRAC3plus.

    26 FILE FORMATS 26.9 MP4 note: this refers to MP4 files as required by the player in the VSH Video Limitation Resolution: 320 x 240 (QVGA), Nonstandard resolutions can be used but are still limited to the 76,800 pixel resolution of QVGA. Codec: MPEG-4 SP (Simple Profile), which has different headers than the more common MPEG-4 formats.

    29 KERNEL MYPROG~2 is the short name for MYPROG~1% The second case works properly. The first does not. Remember why the kxploit trick works at all: the vsh sees a nicely formed file in "MYPROG~1%", but then passes "MYPROG~1" to the bootstrap, which executes the bare ELF.
