Build Info

This is a sub-page of PlayStation 2.

Sandwiched between various things are multiple EXTINFO files, which includes the time and working folder at build-time. As such, it varies per version. The BIOS version column has 2 additional characters at the end, indicating its region and whether it's CEX or DEX. Starting from 02.20, Sony stopped mentioning the release region in the ROM EXTINFO file and simply just used the letter W, likely meaning Worldwide.
