last week, a port of Tranmission 2.94 which is an open-source torrent client. This port is currently in a WIP state and currently only supports FAT32 as using it on an exFAT microSD cad may lead to data corruption and torrent management isnít done on device but through a web interface accessible on any device on your local network. Some hours ago, version 0.2.3 was released which fixes UDP trackers and the replacement of non-ASCII characters in filenames.
You may grab nxTransmission 0.2.3 from this link and make sure to read its GBATemp thread for more information.
