Would you mind providing a link? Is it this? http://www.lik-sang.com/info.php?category=252&products_id=8970& Or possibly this? http://www.divineo.com/cgi-bin/div-us/dd-ds-m3msdnp Also, it won't ruin the DS.
I had one of thoose one time for my DS.. IT works fine you can see movies, hear music, see photos, read e-books.. Once a time i had a 1GB flash card and i set a whole movie on it you can set NES games on it too..
yeah the gbamp is reliable i'e had the cf version for a couple of years now i first got it for my gbasp and now i use it with my nds u can play commercial roms of it with the right tools. all for about 40bucks
that is only the CF version, the picture shown is of the SD version, which you cannot play the ROMs on. Also, you can't use the ROMs on the GBAMP CF on the newer DS's or DS Lite unless the DS is Flashed, but to flash the DS you need a Passkey2, but the Passkey2 dosn't work with the GBAMP ¬_¬
your right you need have your ds flashed or have a passcard to get to play the roms on u're nds i just got the new mini sd version of the gbamp fits into my indiglo blue ds perfectly i thought you were talking about the gbamp http://www.lik-sang.com/info.php?category=6&products_id=3983 but get the other one not the one from lik sang it comes with moonshell installed so you can listen to music and watch movies easy. don't get a passcard 2 get the max media loader from datel is cheaper and works with the gbamp cf cd or mini sd
you can tell b/c one is the gbamp and one is the m3 perfect the m3 comes in 3 or 4 different flavors the cf the slim sd the mini and the new not released micro sd for the nds lite. the m3 plays media ebooks and gba sms ds snes roms and has pda functions. So the m3 is a gbamp for the nintendo ds see the difference http://www.lik-sang.com/info.php?category=6&products_id=3983 http://202.75.33.149/reviews/M3Mini/index.php# i have the mini which fits in my nds flush
The GBAMP comes as a CF or SD version though, and the CF version can, after a bit of hackery play NDS roms. The M3 is made by the same people as the GBAMP and they designed the M3 to play NDS roms perfectly, and this comes as CF, SD, and miniSD - All capable of playing NDS games without any hacking needed.
