SD card reader (preferred), or a way to use wireless file transfer; Installing Checkpoint. Download Checkpoint from the link above. For cia installation, transfer the cia file to the SD card and install it with a cia installer such as FBI. For Rosalina-based Homebrew Launcher, transfer the 3dsx file to /3ds. Now that CDN download is no more, what would be the most efficient way to convert.3ds games to.cia? Any way that could be scripted (say bash or powershell) would be alright for me at least. The reason I ask is that there are 1TB+ torrents around filled with.3ds games, but I haven't found any with.cia games (only one from 2016). .Note - JKSM has a homebrew app available, but The.cia is recommended because the homebrew app may not work with some games. To install the homebrew app, merge the 3ds/JKSM folder containing the JKSM.3dsx, JKSM.smdh, and JKSM.xml file with the 3ds folder on the SD card and use the homebrew launcher to open it. First release - 3dsx and CIA (01 January 2017) - Happy New Year. Installation In the zip there are the Cia file and a folder with the 3dsx and the smdh files inside, to be used with a homebrew launcher. All the resources are included in the executable using romfs. The game creates a xump subfolder inside the 3ds folder if doesn't exist.
convert .3ds to .cia with just an exheader xorpad (old crappy method)
