Alrighty this is what I did to actually get free 3DS game on my o3DS 10.1.
1. You need 2 3DS for this and one of them has to be exploited with kernel access and CFW with unsigned .cia.
2. Install a .cia game to your 3DS with emunand and CFW.
3. Go to eshop on this 3DS and find your game on eshop. Then scroll down and hit 'repair'
4. It will check your game and say nothing is wrong but hit redownload.
5. It will redownload.
6. Now, you have to game forever! Even if you delete the game, you can redownload it on your 3DS again!
7. Now go to system transfer on your other 3DS with sysnand 10.1 and on your exploited 3DS.
8. System transfer the game over but this took me 3 times to work.
I don't know how, but it worked!
