If you are looking for a reliable, modern console to play original discs, or if you plan to use a modchip or OPL-managed network loading (since FMCB is hit-or-miss), the
Early fat PS2 models required a separate memory card utility to play DVD movies, or utilized older, glitchier internal player software. The SCPH-90001 BIOS comes pre-packaged with the final, most robust version of Sony's DVD player firmware. It provides cleaner progressive scan output options and eliminates several playback bugs associated with dual-layer video discs. 3. Streamlined Emulation Performance (PCSX2)

The short answer is . In emulation, newer does not mean faster or more accurate. The SCPH-90001 BIOS will run your games beautifully, but it offers no performance boost or graphical upgrades over a BIOS from a 2001 Launch Fat PS2.
For 99% of modern PC emulation via PCSX2, , but it is not definitively "better" than older revisions.
The best approach, if you are legally able, is to experiment. Try your games with the SCPH-90001 BIOS. If you encounter a strange glitch or issue, test the same game with an SCPH-70012 BIOS. Choosing a BIOS isn't about finding the single best file, but rather the best tool for your specific gaming needs. The SCPH-90001 is a powerful and modern tool, and for many, it will be the perfect fit. I can provide optimal setting configurations based on
For , its newer, highly refined BIOS offers incredible stability and represents the most complete software framework Sony ever designed for the system.
If you are sourcing a BIOS for use with PCSX2, the SCPH-90001 is a top-tier choice. Because it was the final retail version, it contains the most up-to-date instructions for the hardware's OSD (On-Screen Display). In emulation, using a 90001 BIOS often results in: Faster boot times into the main menu.

Without specific details on what "better" or "new" means in this context, it's challenging to provide a definitive answer. However:
Are you planning to use the console for or are you looking to set up homebrew and digital backups ?
The Sony PlayStation 2 (SCPH-90001) represents the final hardware revision of the console, integrating the Emotion Engine and Graphics Synthesizer into a single chip (Dragon). This paper investigates the claim that the SCPH-90001 BIOS is “better” and “newer” than earlier revisions. Through binary diffing, emulator testing, and hardware behavior analysis, we find that while the BIOS is indeed newer (v2.30 vs. v1.00–v1.20 in earlier models), “better” is context-dependent: it offers improved anti-piracy checks, faster DVD read verification, but breaks compatibility with certain homebrew software and modchips. Emulator developers must account for Dragon-specific I/O timing.
