Like a lot of people here I am just trying to figure out what cart is best. Price matters not, I just want the best that does the most. I am interested in DS-X even tho GBA support may be missing. But also interested in movie playback. I read in a thread that NDS slot has lower bandwidth then the GBA slot? Would this affect movie playback? I mean from my understanding the NDS has the cpu power to play full res divx with its two ARM9 cpus. I had a GP2X which had nearly the same CPUs and it played my 700mb divx movies great. So I am assuming the real limitation is the bandwidth on the NDS slots? Anyhow so DS-X would have much slower bandwidth for movie/audio playback? And really how is this possible that more intense games for the DS have lower bandwidth on the DS port rather then old GBA games... hmm thanks in advance for your input.
