MegaKey Region does not save, every power off goes back to JAP NTSC

[keropi]

I have noticed that the megakey region setting in my Mega-ED does not save. No matter where I set it, when I power off the megadrive and then back on it always reverts to JAP NTSC. Is this normal? Shouldn't it save the setting?
I noticed because I was getting japanese text in some games , but when I set it back to US NTSC I get english text - until I power down my megadrive.
Is this a bug?
thanks in advance 


edit: found a trick to get it unstuck from the same setting 

a. turn MegaKey State to OFF and reset , then power-off
b. change MegaKey Region to desired value, reset then power off
c. turn MegaKey State to ON (this time it kept the Region setting) and reset , then power-off

that got it unstuck and now it saves almost every time... I checked it several times and it seems to shift from regions and end up either in JAP NTSC or US NTSC that I have set with the trick above...

Krikkz any info on this? The region keeps changing at me, is it supposed to do that?

I can't reproduce it, for me megakey always stay in state which is was selected. By the way, megakey region re-setup each time when you choose new game, may be you just misunderstand about how is it work? Mapper and megakey options sets automatically when you change the game.

oh I see... so it's not a static setting that depends on what game you select... I thought you set it manually and it was supposed to stay there 
thanks for the clarification!
