Part 20 of the GTA V - ATOM GUY EDITION RAR set, about 3.9 GB, apparently a modified game distribution unrelated to device service. The name refers to no schematic, boardview, datasheet or BIOS, and no hardware. Split RAR volumes work only as a complete set, so extracting requires every part in one folder with a tool such as 7-Zip or WinRAR, starting from part one. A missing or corrupt volume causes CRC errors. For repair work this segment holds nothing useful and can be ignored when looking for board files.
