Best way to manage legacy BIOS files for retro emulation projects?

Hi everyone,
I’m working on a small personal project related to retro console emulation and preservation, mainly focused on older PlayStation systems. I want to make sure BIOS files are organized correctly and handled in a way that stays compatible with different emulators across platforms.
For those who have worked on similar projects or hardware setups, what’s the best practice for storing, naming, and validating BIOS files to avoid errors or crashes? Also, are there any common mistakes beginners usually make that I should watch out for?
I’d appreciate any advice or suggestions from people who’ve dealt with legacy console emulation before
