Maybe I am explaining myself poorly or I'm not understanding you.
I have TwlBg.xci In Luma/Sysmodules. This one is made to start in 1:1 (inverting the use of Start+Select) and has nothing else, really. Whenever I boot Twilight Menu or use one of my own cartridges, the system reads this.
I have Widescreen.xci in _nds/TwilightMenu/TwlBg. From what I read TwilightMenu only reads this if you want to boot up a game in 16:10. This xci file has only the widescreen patch. It has no inverted use of Start+Select.
1:1 only happens either on real carts or in Twilight Menu, unless what you're trying to tell me is that if you boot Twilight Menu in 1:1, then it also borks the Widescreen attempts. I was under the assumption that it wouldn't matter.
If that's the case, then you're telling me that's needed to boot in stretched mode if I want to play something in Widescreen, is it?
Edit: Okay, I tried and it does seem it works that way. If you boot in 1:1 it does screw Widescreen.
Sorry but I just wasn't understanding exactly what you were getting at. Now that I know this I will mess around it more to see what I end up liking the most. Thank you, Sono.
Vendicatorealato, you're right, the last one isn't on Universal Updater, I remember the flashing at the start. Thank you both.
