Could you please release the DSi version with a DSTWO compatibility? (The DSTWO is more powerful than the DSi)
It's not that simple; in fact, I'm pretty sure what you're asking is pretty much impossible. For starters, I don't have a DStwo, but that's not even the main problem : as far as I know, using the DStwo's cpu/ram means completely blocking out the DS's hardware graphics acceleration, which means no access to the 3d gpu, which means no DScraft as we know it. Basically, I'd have to write a software rendering engine just for the DStwo version, and since DScraft is optimized to work on the DS and the DS alone, I'd probably have to completely rewrite DScraft to get the best performance. So no, that's not on the agenda.
(that's despite me actually being interested in writing a software rendering engine)
