You're facing several common issues with Recalbox 9.1 and PCSX2 on your Lenovo M700 Tiny with Intel HD Graphics 530. GTA: San Andreas suffers from camera glitches and visual artifacts, which can often be reduced by using the Libretro PCSX2 core or switching to software rendering mode (toggle with F9). Game freezes are likely due to GPU driver limitations or BIOS/config issues—using accurate BIOS files and checking system temperatures may help. Savestates are currently unreliable in Recalbox’s PCSX2 implementation, so it's safer to use in-game memory card saves. Hotkeys like entering the RetroArch menu or exiting the emulator often don't work properly in standalone PCSX2, making the Libretro core a better choice for consistent controller behavior and hotkey functionality.
