FPGA cores "recreate" the hardware. To function accurately, they require the exact silicon logic from the original console. The ’s all-in-one chip is notoriously difficult to reverse-engineer. Thus, the BIOS file acts as the key. For a portable FPGA PS1 device to exist, it will almost certainly rely on a V18 BIOS dump.

: For portable emulators (like PCSX2 on a USB drive), you must place these files in the BIOS folder within the emulator's directory and select them in the settings. scph90001biosv18usa230 portable

In that case, for the portable build. Instead, you need: FPGA cores "recreate" the hardware
