So, remember the firmware.nds file floating around? It's great for running the DS system menu on the DSi, however it is based on an old DS phat firmware (v3). I took the file and modified it to use the DS lite firmware (v5), so screen brightness should work. Now, I know posting the file is illegal, so I'm just posting a patch so if you already have the old firmware.nds, you can use bspatch to update: http://filetrip.net/f24561-DS-Lite-System-...S-file-5-0.html (make sure to compare MD5). I don't have a DSi, but it works on my Lite. I'm hoping that it works on the 3DS because the 3DS doesn't have PictoChat.
