Guys, these DOL/ELF's that are released are almost 99% open source (just gotta find the link to the source). And no, it's not a simple open notepad and edit a 1 to 0. There is a lengthy process to set up a development enviroment on your PC so you can view/modify/compile the source. Additionally, alot of new releases are built using additional "libs" that are not included in the common dev enviroment package so therefore you have to re-build your enviroment when you do find the libs and want to include them.
Creating/Modifying DOL/ELF's is not for the faint of heart. If you have no interest inlearing C/C++ basics, and don't have 24+ hours just to get your first build tested... Please allow those who do to do their fancy work.
If you ARE interested in learning and becoming an active conrtibutor, head to wiibrew.org and dedicate some time to reading then make your first app

It's not easy at first, but everything you need to begin is readily available.
Have fun
NOTE: Yes I am still learning as well - please don't ask me "How do I make X do Y?"
