I wanted to make a very minor texture hack for Zelda: Phantom Hourglass, basically just to remove the fog effect from certain areas, for the purpose of taking clearer screenshots. I did some quick searching and found a nice DS filesystem explorer called Tinke, which I'm sure some of the regulars on this board are familiar with.
So I found the fog texture easily enough (.nsbtx format), extracted it, used a hex editor to "black out" most of the image, then reloaded it into the ROM with Tinke. No issues so far, and viewing the edited texture in Tinke shows the desired effect. Then I saved a new copy of the ROM, but when I tried it in DeSmuME, it hangs at the white screen and doesn't get anywhere.
I assumed there would be some kind of signature or checksum process that Tinke would take care of, but if anybody here is more familiar with the process and knows what went wrong, could you please help me out?
Once this is working, I'd also like to black out the glowing textures when Link holds up a new item, but I haven't been able to find them in the ROM.
