First things first, does it matter whether it's US or EU version? DSi XL has no GBA slot so I'd be using it on my good old Lite which isn't region blocked. Just wondering if it affects chaining (if a EU Platinum picks up a US Ruby as an example) or palparking.
I first checked eBay for a Ruby but I honestly don't trust to get it from there with all the bootlegs around.. I'd rather not risk it. I don't mind if it's game cart only, box and booklet aren't necessary at this point.
Found, thank you so much! <3
