OpenPS2BIOS 0.2

Fixes Gran Turismo 4 startup by running IOP module entry points at the correct loader priority. This prevents its INET worker from preempting initialization and looping on uninitialized semaphore IDs.

GT4 (USA) was verified to reach its memory-card prompt through fast and full boot in PCSX2 2.9.94. Gameplay has not been verified.

OpenPS2BIOS 0.1

First public release of OpenPS2BIOS, an experimental replacement PlayStation 2 BIOS for emulators. It contains no Sony firmware.

Warning

For emulator use only. Do not flash or install this BIOS on a real PS2. It does not initialise the console's memory controller or other hardware that emulators set up on their own, so it will not boot on real hardware.
