Thanks to it's processor emulating an official game cart, I can play Pokemon Black without a single AP patch! No other DS cart does that (memory patches don't count).
Oh yeah? Well I spent 20 bucks on my R4 3 years ago and it still plays pretty much all the games (thanks to Wood). No other flashcart has lasted that long. Thats why my shitty old original R4 is awesome!
All other carts can't play Pokemon Black without an AP patch. The newest updates for most carts have the patch built in, but it's still just a patch, the DSTwo doesn't patch the ROM at runtime at all.
