Hello everyone! I am new her to these forums and an up and coming modder, (If thats the right way to say it) I have done a project before. I softmodded a nintendo Wii console. I have been wanting to make a portable GameCube for some time now and after reading all of the great modders here on this forum, Im gonna do it! I just have one question, I am following Kasar's GameCube portable tutorial. I understand everything, however I don't want a disc drive for my portable which make things harder over all. So my question is, what can I do to replace it? I know a little about the Wasp fusion and loading from an SD card, I just need to understand a couple of things. Also, where I could buy these parts? Again thank you so much guys! This forum is really awesome!! The tutorials are so easy to understand and the admins and community are so helpful! 
edit: Also, from Kasar's tutorial it says for the controller wiring that to wires need to go to the + and - of the bios battery but I can't seem to find it anywhere.
