To flash something new you need to provide a mapping.map and a flash.bin file either from your backup, from another NP cart or you can create those files with the SF Memory Binary Maker: https://github.com/moldov/SF-Memory-Binary-Maker
In the second case rename SHVC-MENU.bin you got from NP Split into menu.sfc and copy it next to the .exe. You can also use a Hex Editor to cut-out the first 512KB of your original flash dump and rename it to menu.sfc instead.
In SF Memory Binary Maker you got two options: either create a standalone map file from a single rom up to 4MB or you can add multiple roms and create a combined .bin and .map file. The sum of all the roms together can't exceed 3.5MB however since you still need 512KB for the menu.
In SF Memory Binary Maker you got two options: either create a standalone map file from a single rom up to 4MB or you can add multiple roms and create a combined .bin and .map file. The sum of all the roms together can't exceed 3.5MB however since you still need 512KB for the menu. Roms need to be unheadered and have a valid checksum.
In any case you should end up with a 512B map and 4MB bin file, rename both so their filename is very short and without any special characters and copy them to the root of the SD card. Switch the NP cart into HIROM ALL, unlock WP, erase the mapping, erase the flash and then write the mapping and write the flash.
