Description

Some games require 2.5mhz, some require 5mhz.
Pressing and holding END while Resetting the system sadly doesnt work for me.
I tried enabling Game Focus Mode, checked END wasnt a hotkey for anything, but sadly no luck.
I manually editted the np2kai.cfg

"DIPswtch = 3e e3 7b " for 2.5mhz
"DIPswtch = 3e f3 7b " for 5mhz

Exposing this setting in the UI would make it simpler, since we could then configure it on a per-game basis. Even for those where "END + Reset" worked this would be a huge help.

Research direction

Start by tracing the RetroArch UI and per-game configuration path; the issue identifies np2kai.cfg and the DIPswtch values for 2.5mhz and 5mhz. Done means exposing this GDC clock choice in the UI and allowing it to be saved per game, with both clock settings selectable.
