MarcaDS_V40

hi, i downloaded this emulator (MarcaDS_V40) put it in the root of my card and i have gone to play one of the games in the MARCADS folder and it doesnt show up on the DS. can somebody please help me on how to play these games (the games are: space invaders, Super pang world and pacman) i use a CycloDS 1.56 beta 4 and a 4GB Kingston SD card. if that helps. please help

I have never heard of this emulator...is it for arcade/mame games?Did you follow the included instructions?If they are mame/arcade roms...did you extract them or leave them as is?With mame/arcade roms your meant to leave them inside the zip they came in, and to NOT change the file name.

oh thanks i took them out of the zip i will try this
