Download the patches first:
Extract the archive and in the "radar" folder, you will find two patches, one for black 2 and one for white 2
If you want to use Dream Radar with Black 2, use the black2.ips, and if you want to use White 2, use the white2.ips
On your SD card, in the luma folder, create a "titles" folder, and inside that folder, make a folder with 00040000000AE100 as the name.
put black2.ips or white2.ips inside that folder, depending on which game you want to use Dream Radar with. For th is example I will use white2.ips
Click once on the patch file, and press F2. This will highlight the filename and allow you to change it.
Rename this to code.ips, and press Enter to confirm
At this point the patch should be in place. All that's left to do is to create a "roms" folder at the root of your SD card, and inside that folder, create a "nds" folder. In the "nds" folder, create a "saves" folder.
Put your save file inside that folder, and rename it to black2.sav or white2.sav, depending on the version of the game you want to use Dream Radar with (if you want to alternate, you will have to replace the ips patch with the other version first!)
Now you're done setting up your SD card. Put it back into your console and hold Select while powering on. On the Luma configuration screen, you want to ensure that "Enable game patching" is activated (use Up and Down on the d-pad to navigate to it, and press A to make an (x) show up.) Then press Start to save the configuration and boot into the system.
That's it, the patch should work and you should be able to use Dream Radar with your save file on the SD card.
