K im confused here.
For the DS, if you have an R4 card do you need a Micro SD as well?
Or can you just have a Micro SD alone or an R4 alone??

You need both.

The R4 card looks like the regular cartridge that you buy for authentic games on the DS. Then you slip in the Micro SD into the R4 card. The Micro SD is where all your NDS game files are. Without it you'd have no games.

u need the micro sd for the R4. im actually sellin those kinds of stuffs but only here on the island. there r different kinds of R4s. I've experimented and used basically different kinds like the R4, DSTT, M3Reals, M3simply, DSone, etc. they all do basically the exact same thing, juss different companies. ppl juss get the R4 coz it's mostly the common one. i dnt think it's the best though. it also depends on if u wanna play games only or if u also want the music and movie features.

I'm waiting till they get these to work with online play.

K I'm confused here.

If I have a Nintendo DS, but the only games I have are New Super Mario Bros. (already beaten) and SimCity, should I buy a new game (can't afford one) or shoot myself now?

Shoot yourself. That's what I'd do if I was faced with having to buy a game...gasp!

Although it looks like I'm going to have to suck it up for Guitar Hero.

if u hav those R4 stuffs then u can get all the ds games for free like i do lol. i hav like all the games free lol. u can download them online.

So if everything is stored on the Micro sd, then what's the point of the R4?

Btw are they still sold in the US? Supposedly nintendo was losing $ so they took them off the market...?

the micro sd is the same size chips like those u use for ur fone. the R4 is the same size as a regular ds game. u cnt play the micro sd on a ds without the R4 coz the ds dnt hav slots for the micro sd. so u need to put the micro sd in the R4, then use the r4 like regular ds cartridge

The micro SD is tiny (hence the name). The R4 card looks like a game cartridge. Without the R4 card you have no means of using the micro SD card as it doesn't fit anywhere in the DS.

Bottom line, it goes Micro SD card --> R4 card --> Game cartridge slot in your DS.

I don't know if the R4 card is still sold in the U.S., but the last time I went to Hong Kong, the prices for it went up the roof because the manufacturers were suffering some (obvious) legal problems and stopped production indefinitely. Nintendo is obviously losing money as long as the R4 card exists. And Nintendo does not make these R4 cards. Think about it, they are cards that you use so you can avoid buying real games.
