So from what I understand, RXTools is a custom firmware that does not require a flashcart. I have also read that you can boot directly into RXTools (unlike gateway). Right now, I have a O3DS with sysnand 4.2.0 and gateway updated to the latest emunand. Does RXtools boot into the present custom firmware on the SD card, or will it install a new custom firmware all together? That being said, if it's it's own thing entirely, will my gateway card and games stored on it be read by this custom firmware? And will exiting system settings boot back into sysnand like it does with gateway? Thanks in advance for you help
