Next always defaults to YM

[zork]

Hi,
I am trying to change the apparent default from YM to AY on KS2. It appears I can do that from NMI menu once the system booted but the setting is not persisting across reboots.

I have tried to do it from the boot menu (hit space while booting), but whatever I choose there and can see in config.ini is not reflected when I hit NMI button later. NMI menu always shows YM as default.

Any way to change the default YM to AY so it persists across reboots?
