sorry i keep commenting but i keep forgeting to put stuff and they really need an edit button on the comments, I would say PSP. You could hack it unlike the DS. The only thing for DS is R4 for hacking and you have to buy it online for about 60$. you can hack it unlike the ds... no you just haven't found a way to hack it yet.
all you need to do is hack your psp and you can get any nintendo game on your memory stick. ds is just so dumb its a handheld for little kids
If you think it is a dumb handheld for little kids than why would you hack it for DS games? Why would you hack it period is the question, it shortens the PSP's lifespan.
ds all the way psp is to old ds is much better and has much funner games psp has not good graphics sooo ds i dont have one but my brother does its awesome
