Yes it's safe.I see in diferent webs Game boy Advance games in .cia format
Not the official release games I say inject gba roms to play in 3DS
Its safe install and play those games?
Thx in advance
Also if you have some GBA ROMS, or find some that you want that aren't in CIA format already, you can inject your own with this:I see so now I can install some GBA games
