[QUOTE="Nicknine, post: 9613671, member: 552047"] Based on my observations, the first 0x200 bytes in firmware dump are unique per console (but not affected by user settings). I guess this area contains console ID or something along those lines? Cutting off the first 0x200 bytes and the last 0x600 bytes gives me the following known hashes: v3 (8:51 Feb 28 2005) - 7e8081ae21b7cb91b3127823be655c68 v4 (14:48 Jun 6 2005) - 80c856ed92ebe09c1d93f09fd895b42a v5 (21:33 Feb 5 2006) - dc93ed168c94755140d748b19aa6bbd7 <----- First known DS Lite firmware v5 (11:19 Mar 8 2006) - 744a1d789278a589484240121899d4c3 EDIT: There is some useful information here: [URL]https://problemkaputt.de/gbatek-ds-cartridges-encryption-firmware.htm[/URL] 00000h-00029h Firmware Header 0002Ah-001FFh Wi-Fi calibration data 00200h-3F9FFh Firmware Code/Data 3FA00h-3FAFFh Wifi Access Point 1 3FB00h-3FBFFh Wifi Access Point 2 3FC00h-3FCFFh Wifi Access Point 3 3FD00h-3FDFFh Not used 3FE00h-3FEFFh User Settings Area 1 3FF00h-3FFFFh User Settings Area 2 From what I'm seeing in the files, firmware header and firmware code are consistent per version while Wi-Fi calibration data is per console (contains stuff like MAC address).

I feel like school, back when I was actually in school, was more entertaining though, because of how much I get to interact with people, hang out with friends, and other stuff like that. All I get to talk to at work is my boring coworkers lol
