If you don't understand what it has to do to with this part of the board rather than the testing area... You'll know soon enough P.S. : the first one to comment about the color of my DS will get his ass kicked, badly. Apparently people don't get it. So this is the process around it. (After all, making this kind of hack directly is cheesecake). It was to present my incoming proggie I announced on this board. I start things up by opening the nds romfile into my prog : Then I start looking a bit at files, and find some interesting filename here : So a right click on the raw data and find some probable data structure : Some config pops up : Oh! some rhac type image file here : A little right-click and choose export data : we name it bla.png, but we could choose any known file format here (handy lib) The image exported is here : and we want to replace it with this one : Then just import it (menu shown earlier) : And we just click patch, that's it !
