If you must use a BIOS file and own the hardware:
If you physically own a Japanese SCPH-90000 PS2, you are legally entitled to dump (extract) its BIOS for personal backup purposes. Many countries have laws allowing "archival copies" of software you own.
Here is how to legally extract the BIOS from your own console.
Modern PCSX2 builds can bypass region checks via the Region patch in the game’s .pnach file. You can use an NTSC-U BIOS to play Japanese discs if you apply the correct patch—but text will display garbled if the game expects Japanese fonts.
The 90000 series (often called the “Super Slim” before that term existed) integrated the power supply directly into the console, unlike the external brick of the 70000 series. More importantly for emulation: Ps2 Bios Japan Scph-90000 Download
The search for a “Ps2 Bios Japan Scph-90000 Download” is understandable—it represents the peak of PS2 engineering in its most final, efficient form. For the dedicated emulation enthusiast, nothing beats the authenticity of booting a Japanese disc on a properly configured PCSX2 with that specific BIOS’s white startup cubes and serene Japanese text.
Yet, we must emphasize legal and ethical preservation. Do not download BIOS files from shady ROM sites. These files are often tampered with, contain malware, and disrespect the intellectual property of the engineers who built the PS2. Instead, invest in a used Japanese SCPH-90000 console from a second-hand shop or auction site. Extract your own BIOS. Become part of the preservation community.
The PS2’s legacy lives on through responsible emulation. Handle that BIOS file as the important piece of computing history that it is—and enjoy the timeless games of Japan’s golden RPG and action era, exactly as they were meant to be played.

Bedankt euch bei deutschen Abmahn-Anwälten
Leider passiert es immer wieder, dass Abmahnungen für angebliche Copyright-Verletzungen ins Haus flattern. Ganz häufig ist es der Fall, dass auf dem Frontcover ein Foto oder eine Grafik eines Fotografen oder Künstlers genutzt wird, was dann nur mit dem Namen der Band und dem Titel des Albums versehen wurde. Das ursprüngliche Foto/Kunstwerk ist somit immer noch sehr prominent zu sehen. Die Abmahner nutzen zumeist automatisierte Prozesse, die das Netz nach unlizensierten Nutzungen der Werke ihrer Mandanten durchsuchen und dabei Abweichungen bis zu einem gewissen Prozentgrad ignorieren. Somit gibt es also häufig angebliche Treffer. Obwohl das Foto/Kunstwerk von den Plattenfirmen oder Bands ganz legal für die Veröffentlichung lizensiert wurde, ist dies den Abmahnern egal, ganz oft wissen die ja nicht einmal, was für eine einzelne Veröffentlichung abgemacht wurde. Die sehen nur die angebliche Copyright-Verletzung und fordern die dicke Kohle.
Da Musik-Sammler.de nachwievor von privater Hand administriert, betrieben und bezahlt wird, ist jede Abmahnung ein existenzbedrohendes Risiko. Nach der letzten Abmahnung, die einen 5-stelligen(!) Betrag forderte, sehe ich mich nun gezwungen drastische Maßnahmen zu ergreifen oder die Seite komplett aufzugeben. Daher werden jetzt alle hochgeladenen Bilder der Veröffentlichungen für NICHT-EINGELOGGTE Nutzer verpixelt. Wer einen Musik-Sammler.de Nutzeraccount hat, braucht sich also einfach nur einmal anmelden und sieht wieder alles wie gewohnt.
