First, I want to thank you for the reply, Fast6191! Your link has an usefull information that is how the console works on the header of the games.
AK2i was abandoned when DSi was at ver 1.4.4, thats why isn't a firmware to work on 1.4.5
, my little brother made an fm atualization on my DSi when he was playing, I don't know why he did this, but when I saw that there's no patch for it, I went in a little "madness" because I like A LOT the Acekard and AKAIO kernel... It works really fine! And then I started to search a little to try something on it with reverse engineering, (I have some knowledge on it since I graduated on i.t)
INSIDE FIRMWARE ARM9.bin file:
I really need to find where on this Firmware are flashed the header information of the game that is used to exploit, by preference I'm using
inside it I found an sequence of Binary lines, I think that is on this sequence that is flashed the header
here it gets an header but I dunno if it is from the flashed game "DORASU" or just the header from the firmware "rom"
