Can OpenBIOS Compensate for HLE BIOS Limitations?

[davidhedlund]

"In case the PCSX ReARMed core can find no BIOS files named like this in RetroArch's system directory, it will default to a High-Level Emulation BIOS. This decreases the level of compatibility of the emulator, so it is recommended that you always supply valid BIOS images inside the system directory." - https://docs.libretro.com/library/pcsx_rearmed/

The PCSX ReARMed core is forked notaz/pcsx_rearmed which includes OpenBIOS is.

Questions

• Can OpenBIOS compensate for the emulator’s reduced compatibility?
• OpenBIOS is designed to be a fully compatible replacement for the stock BIOS, making it generally region-free when used in emulators. Is this possible with the current HLE BIOS?

How to test OpenBIOS

• Download the latest AppImage from https://distrib.app/pub/org/pcsx-redux/project/dev-linux-x64
• Extract the Appimage: ./PCSX-Redux-HEAD-x86_64.AppImage --appimage-extract
• Copy the openbios.bin file from the generated directory squashfs-root/usr/share/pcsx-redux/resources
• Renename openbios.bin to scph5501.bin
• Place scph5501.bin in your RetroArch System/BIOS directory.
