Finally you can split the flash.bin file into the individual roms using the NP Split program: https://github.com/sanni/cartreader/tree/master/extras/npsplit Finally you can split the flash.bin file into the individual roms and the menu using the NP Split program:

To flash something new you need to erase both the flash and the mapping first before you send the write command. Flashing the Nintendo Power Cart is more complicated since you need to provide it with a mapping.map and flash.bin file. You can create those files with the SF Memory Binary Maker: https://github.com/moldov/SF-Memory-Binary-Maker To flash something new you need to erase both the flash and the mapping first before you send the write command. You also need to provide mapping.map and flash.bin files on your own.

In this 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.
