No, you can't
No, but it helps if you want to store a lot of media because the DSi only has a limited amount of space. But music can ONLY be stored it on a SD card and NOT the DSi's memory.
NO, a PSP's memory stick is a memory stick pro duo. A dsi's is a sanDisk
yea you can download it on romulation.net and save it to your computer. Then have an R4i chip, which will be the game you insert in the dsi, but you will save the downloaded game on a memory stick from your computer. The memory stick will be inserted in the R4i chip. Hope it helps
nintendo ds: no nintendo dsi: yes(but needs acompatible memory card)
nope psp takes memory stick pro duos, dsi takes sd cards :)
No, you do not.
Yes.
No, the only things you can insert in a DSi is headphones/ ear plugs, a game and an SD Card.
Yes, in fact the only slot on a DSi is for DS games.
Yes, the DSi (and XL) use the same memory cards as the Wii does.
It doesn't 'need' a memory card (Memory Stick is a Sony card, the DSi uses SD cards), you can play games without using one. A memory card would be for storing lots of photographs, MP3s or DSi store games.
If you mean Nintendo DSI XL, then just insert it in your DSI XL YOU DUMMO!
