I have copies of the TTMENU.DAT files that come with both the original TTMenu and YSMenu renamed to TTMenu.nds and YSMenu.nds respectively. You can then run one from the other without rebooting, so if you want to change the brightness you can just boot up TTMenu.

I'll have to give this a try, thanks!
Any idea, once the brightness is changed does it then stick when you reload the YSMenu, or do you hav eto launch the games from the official TTMenu? I suppose it is too much to wish for that the brightness change sticks after a reset!
EDIT: Ok, I jsut tested it out, and it seems that the changes do stick between soft resets, but not after a shutdown. One interesting thing is that once I set the brightness in the official TTMENU that it sticks. So once I have it set to low, then the next tiem I turn on the DS all I have to do is click the TTMENU_official.nds, it loads at the brightness I had specified before, then I can right away click TTMENU_ys.nds, and it loads back into the YSMENU at that lower brightness.
Just to be sure, doing this isn't putting both the menus into the memory is it?
