So i have a Nintendo DSI XL and an R4 v1.4.1. And i used it a few years ago and it was fine, i came back to it today and it says 'An error has occurred', I've tried installing the firmware on it, i tried V1.82b and V1.44b (which looked promising as it was the one that came out at a similar time to my R4). NOTHING SEEMS TO WORK!! What is the issue? do i need to add more than just the firmware before trying it? i reset my DS to factory settings, so i don't know what to do! PLEASE HELP!
