if you mean stylus then yes for some games
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.
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
no you can't play dsi games in ds but you can play ds games in dsi.

YES, THE DS AND THE DSI can play toegether.

Nope. They use SD cards though. Get your PSPs and DSi's right!
You can play that game on the Dsi. I would know because I play it on the Dsi all the time. Spmething is probably wrong with your DSi.
