About Us

We built PS2 BIOS because setting up a PS2 emulator is harder than it needs to be. The emulators themselves are good. PCSX2 in particular has come a long way. But the first hour with one is still a pile of small things that can go wrong: a BIOS file that isn't where the app expects it, a folder with the wrong capital letter in its name, a black screen with no error message at all. Most of us have lost an evening to one of those, usually because the guide we were following was written for an older version of the software.

So this site is our attempt at the guide we wanted back then. Plain steps, written for people who just want their games to start, and updated when the software changes.

What we write about

Mostly emulator setup and troubleshooting. That covers PCSX2 on Windows, macOS and Linux, the Android options that appeared after AetherSX2 was discontinued, RetroArch, and handheld setups like the Steam Deck. We write about BIOS files, folder paths, controller mapping, graphics settings and the occasional compatibility quirk that only shows up in one or two games.

Now and then we also write about the console itself, such as how the different PS2 models and regions relate to each other. That background tends to make the practical advice easier to follow, because you can see why a step exists instead of just doing it because someone said so.

What we don't do

We don't host BIOS files, game ISOs, ROMs or anything else that belongs to someone else, and we don't link to sites that do. That isn't a technicality. The PS2 BIOS is Sony's software, and the PCSX2 team says plainly that you should dump it from a console you own. Our guides walk you through doing exactly that. If a page ever seems to point somewhere it shouldn't, tell us and we'll fix it.

We also try not to pretend a guide is finished when it isn't. If we can't confirm a detail against an official source or our own testing, we say so, or we leave it out. A confident wrong answer about a folder path costs you more time than no answer at all.

How we keep things accurate

Before a guide goes up, we check it against the emulator's own documentation. When a detail comes from somewhere else, such as a hardware reference or a release announcement, we link to it so you can see where it came from and judge it yourself. Everything is read and edited by a person before it's published.

Emulators change quickly. A step that was right last year can be wrong today, and we'd rather update a page than leave an old one sitting there looking authoritative. If you spot something out of date, the contact page tells you how to reach us. We read every correction, and when someone points out a mistake, we fix the page and say so where the change matters.

Who we are

PS2 BIOS is run by a small group of people who like playing and tinkering with older consoles. We're players first. Some of us have a shelf of original PS2 games and a console or two that still works, which is how we ended up learning how BIOS dumping really goes. Others got into this by trying to get one stubborn game to run properly on a laptop and not stopping until it did.

We're not professional developers, and we're not affiliated with Sony, the PCSX2 project, or any other emulator team. PlayStation and PS2 are trademarks of Sony Interactive Entertainment. We use those names only to describe the hardware and software our guides are about, and nothing here is endorsed by their owners.

Why the guides are written the way they are

You'll notice the guides lean toward short steps and straight answers. That's deliberate. Most people reading a setup guide are halfway through a setup, with the emulator open in another window, wanting to know the next thing to click. So we put the instructions first, keep the history lessons short, and add a troubleshooting section where we know people tend to get stuck.

We also try to be honest about trade-offs. A graphics setting that looks great on a gaming PC might be too heavy for a budget phone, and some games need their own tweaks no matter what you do. Where there isn't one right answer, we tell you what the options are and what each one costs you.

Get in touch

If something in a guide didn't work, if you've found a mistake, or if you just have a question about your setup, head to our contact page. It lists what to include in a message so we can actually help, and what we're unable to help with. We can't promise a reply to everything quickly, but we do read everything.

Thanks for stopping by, and we hope your next game boots on the first try.
