Description

I was playing a lot this weekend and noticed CPS2 games save BIOS (diagnostics menu) settings just fine.

CPS3 and Neo-Geo do not. I'm pretty sure CPS3 did save settings at some point. Tried Neo-Geo with the regular BIOS and Universe BIOS.

Research direction

Start by reproducing the settings-save behavior in CPS3 and Neo-Geo games, comparing it with CPS2 BIOS diagnostics settings. Check both the regular BIOS and Universe BIOS paths mentioned in the report. Done means CPS3 and Neo-Geo BIOS settings persist after restarting the game, with regression coverage added if the repository provides relevant tests.
