PS3 PS2 Bios mods?

https://retrogamecorps.com/2023/02/17/ps2-and-ps1-bios-extraction-guide/

Anybody tried the extracted bios with pcsx2?

PS20220WD20050620.crack is used by PS2Classics & ps2_netemu.self/.elf?

I know somebody already extracted & repacked the bios files with the Xmodules for extra homebrew compatibility for netemu but I was wondering if it'd useful for debugging/testing the bios on pcsx2 to workout the differences to the earlier software emulator? if we can extract & run both bios versions in pcsx2.
Maybe reimplement the full missing osdsys files also.
According to the tutorial video the extracted bioses only work in fastboot within pcsx2.

Research files ;-p feel free to upload to a better host.

I've managed to rebuild the ps2_netemu bios using romman https://github.com/israpps/romman
with the extra osd modules from ps2_softemu but it's still complaining that it's missing something when I try to load the replaced osdsys from it, I think it has something to do with OSDCNF.

I'm not sure but I think when I tried to include TZLIST or PS1DRV it wanted change the offset of RDRAM, IOPBOOT or REBOOT.
