With the help of their friend WAIN, Team Xectuer released a useful custom homebrew app for SX OS: The SX Dumper, which will allow you to dump an original game to your microSD card or USB HDD and then play directly with your backup without the need of the original game anymore.
Let’ see the features about the SX Dumper v1.0.0:
Dump to .XCI
Automatically filenaming (full gamename.xci)
USB HDD & microSD Card support
Trimmed dumping (removed unused space from backup)
Splitting files for FAT32 filesystem
CRC checking dumped image
