Quick summary - I have RxTools 2.6 on EmuNand, and I can run cias just fine. I've heard you need to install GBA cias to both SysNand and EmuNand for them to work, so I've tried doing that. On FBI, I chose to install the cias both to SD and NAND, but all that did was create un-ending gifts with black boxes in the home menu. So I figured I had somehow to install FBI on SysNand, and proceeded to do it through the RxTools menu. After a supposedly successful installation, I went to SysNand and tried using the Health and Whatever app to access FBI there, but it just opens the normal app. My SysNand is on 4.2. I've even tried installing it manually, like a post from gbatemp would advise, using 3Dnus and injecting it into the SysNand dump, but I couldn't find a way to reinject the dumped NAND to the SysNand. I have made videos for the Brazilian audience showing how to downgrade and then install RxTools, so I'm contributing to the scene somehow. Now I'm the one who needs a hand! What should I do?
