How to get PlayStation 1 or PlayStation 2 BIOS without a console

If you want to emulate PS2 or PS1 games, you will need a BIOS. Here’s a quick and easy way to get one legally.

The PlayStation 2 is a nostalgic console for many people, but it can be hard to emulate. If you don’t tweak your console and flash the BIOS, you won’t be able to emulate games by the likes of AetherSX2. Now, it turns out that it’s possible to download and extract BIOS from official PS3 firmware with a little bit of work.

These steps are written for Windows, but they are quite similar for Linux as well. This is important because flashing the PS2’s BIOS requires something like FreeMcBoot, but dumping games can be done with most traditional disc readers on a PC.
