Help me with PS and PSP emulation

After replacing the SD card, I’ve had no issues with lighter titles and have been enjoying the ported games. However, for PS games, I’m encountering a "PS BIOS not found" error, which is causing problems like Tekken 3 getting stuck at the main menu and other glitches.

Additionally, in PSP games, the controls have been swapped from the BAXY configuration to AXYB, making gameplay challenging. Could someone kindly share screenshots of the correct control settings in PPSSPP to help resolve this and help me with the PS emulation issue also..?
