Duckstation BIOS

[Kamako]

Your BIOS file mimics the region version of the console. A JPN BIOS file is compatible with JPN roms. I'd recommend sticking to a worldwide BIOS file if you intend to play games from multiple regions.

It's here alright!

Yeah, it's not only a pack, it has separate bios versions.

It doesn't matter which BIOS you have all you need is one to do the job.
I'll tell you what, since I'm a nice guy, I'll hook you up with this. I get it here. @ https://distrib.app/pub/org/pcsx-redux/project/dev-win-x64
Or use original scph-1001, your choice.

Nah it's fine, even though it didn't have a difference.

Okay, suit yourself. Info here @ https://pcsx-redux.consoledev.net/openbios/

Don't get me wrong, I like the boot sequence, some games work with it. Info here @ https://docs.google.com/spreadsheet...tUdcowGsjcVc/edit?gid=772799649#gid=772799649

Oh alright beeeeet!

@Zero_X - From experience, I can tell you that a single BIOS for all games is the easiest and fastest way to emulate titles. However, it can also cause problems with certain games...
The best way is to provide DuckStation with 3 BIOSes: personally, I use SCPH-5500 (JP), SCPH-5501 (US), and SCPH-5502 (EU), and everything always worked and works great

I would follow OPT1MUS advice regarding the BIOS since its an easier setup

Tu archivo BIOS reproduce la versión regional de la consola. Un archivo BIOS JPN es compatible con ROMs JPN. Recomiendo usar un archivo BIOS global si quieres jugar juegos de varias regiones.

Is the SCPH 1001 only for Japanese consoles? It worked for me on Epsxe for all the games.

SCPH-1000 (Japan)
SCPH-1001 (USA/Canada)
SCPH-1002 (Europe/Oceania)

Nope, the SCPH-1001 is not for Japanese consoles, it is actually the North American launch model of the PlayStation.

• SCPH-1000 → Japan
• SCPH-1001 → North America
• SCPH-1002 → Europe

@Zero_X - Por experiencia, te puedo decir que una sola BIOS para todos los juegos es la forma más fácil y rápida de emular títulos. Sin embargo, también puede causar problemas con ciertos juegos...
La mejor manera es proporcionar a DuckStation 3 BIOS: personalmente, uso SCPH-5500 (JP), SCPH-5501 (US) y SCPH-5502 (EU), y todo siempre funcionó y funciona muy bien.
View attachment 100113Now I understand, that should work, but the emulator with three BIOSes is very demanding. But anyway, let's try.

You mean the last one, SCPH 5552? Because I can't find 5502.

Duckstation doesn't work for me on Android 13, at least not for me.I am referring to the BIOS, while Epsxe presents problems to many users like me with the audio and, and its timing.All I can do is play Duckstation without the BIOS.

@Zero_X - They change based on variations/updates/adjustments made in the countries they were intended for (if you notice, the Japanese one is unique).

Anyway... here it is (the "PSX-BIOSES" file I attached contains all 3)

DuckStation on Windows

@Zero_X - Cambian según las variaciones/actualizaciones/ajustes realizados en los países para los que fueron pensados (si te fijas, el japonés es único).

De todos modos... aquí está (el archivo "PSX-BIOSES" que adjunté contiene los 3)

I'm a genius! I finally got the BIOS working properly! And just by choosing the one that used SCPH 1001. The solution is simple, even the Emulator makes it clear to you when you open the BIOS for the first time.

Damn! I could even be a programmer.

@Zero_X - Hey, glad to know!
The SCPH-1001 is essentially the direct descendant of the Japanese SCPH-1000: it can practically be considered the father of Western PlayStation BIOSes. It's very reliable, as it's essentially a revision of the original Japanese BIOS for the Western market.
However, over the years and with increasingly demanding games, this BIOS could cause sporadic problems too, so... I recommend to also keep the BIOSes I provided you handy (actually, you can put them all together in the BIOS folder, given that DuckStation autodetects the most appropriate one for each game)
