Hello folks! I'm a software developer so I got some experience in programming. I bought my little brother a R4i SDHC flashcard but I'm not satisfied with the kernel R4i SDHC offers so I want to write my own. I only found entires/tutorials/code for developing "homebrew" and afaik (I don't have any Nintendo programming experience) this isn't the term I'm looking for. The R4 kernel got a "R4.dat" file in the root folder - I guess thats the bootloader/entry point for the kernel (Please correct me if I'm wrong). I'd be thankful for any resources/links/help you can provide me! Greetings, UnsungDev.
