Wait, but GTA Chinatown Wars was released in 2009 for DS and then ported to 3DS in 2011. By 2021, there's a chance that maybe a QR code was part of a retro promotion or a collector's edition. However, I'm not aware of any active promotions for GTA Chinatown Wars on 3DS in 2021. The 3DS was being phased out around that time, so it's possible that any QR code would no longer be active now.
