They should be, if they're not I'll update them. What cart are you looking for? I used to get my Supercards at Modchipcentral but they seem to be forever sold out anymore. You can try
dsflashcart.com -- shady name aside, they seem reputable from what I've read online and ship international.
You're probably looking for an R4i Gold (or whatever the new ones are) or a SuperCard DSTwo+ (original is discontinued) all things considered.
Don't bother paying extra for the memory card, I've never had one come in. Spring for a 64gb MicroSD and you can fit 100's of DS, GB/C/A games, and lots of homebrew on one cart, but any size will do for DS stuff.
To be fair though I haven't had to replace my carts in like three years so take what I say with a grain of salt!
