When Gran Turismo is purchased from the PSN, it is packaged as a "PGD" (PlayStation Graphic Data) encrypted image. The Eboot is not raw assembly code; it is a ciphertext. The header of the ISO embedded within the Eboot is encrypted with Sony’s NPUMDIMG scheme.
Released in 2009, Gran Turismo (often referred to as Gran Turismo PSP ) was a technical marvel. Developed by Polyphony Digital, it managed to render 800+ car models and 35 tracks on hardware originally released in 2004. Unlike its console siblings, the game was distributed both via physical UMD (Universal Media Disc) and digitally via the PlayStation Network (PSN).
