thanks. Turns out the file were not visible when I was checking using NXMPT, but I could see it now I got the SD card out lol.
but now the problem is, the file I dumped (a trpfs format) is split into a folder format with two files inside. How do I merge them back together again so it becomes a proper trpfs file?
You can simply concatenate them
(You will need to do this on a file system that can handle files > 4GB of course...)
