This is a c++ equivalent of the original sdat2img by xpirt - luxi78 - howellzhu which was written in python

sdat2img <transfer_list> <system_new_file> [system_img] [-q]

• <transfer_list> = input, system.transfer.list from rom zip
• <system_new_file> = input, system.new.dat from rom zip
• [system_img] = output ext4 raw image file
• [-q] = quiet mode

This is a simple example on a Linux system:

~$ ./sdat2img system.transfer.list system.new.dat system.img
