Grand Theft Auto IV was released in 2008 for the PlayStation 3 (PS3) and Xbox 360. It utilizes the Rockstar Advanced Game Engine (RAGE).
PPSSPP is a Low-Level Emulator (LLE) specifically designed to translate MIPS instructions used by the PSP into the architecture of the host device (ARM for Android/Windows). It cannot emulate the complex PowerPC architecture of the PS3 or the x86 architecture of the PC. Therefore, the actual Grand Theft Auto IV game code is incompatible with the PPSSPP emulator. Running GTA IV natively on a PSP emulator is technically impossible due to the vast disparity in hardware requirements and instruction sets.
