UMC + MaxMedia Launcher

[RavenMaster]

Hi
i'm new at this world :)
just bought the MML and your Ultra Media Card but i'm having a little problem running *.nds

i run .gba very well but i can't open any .nds
i copy the games with your software but the console doens't open it
the screen only stays black
the only .nds i can open are the demos supplied by ndsgba

i've tried 8mb, 16mb and even 64mb games and none of it runes

just tried to update firmware again :(

help ?

with a new RS-MMC, i formatted in FAT, downloaded the software (didn't use the cd one), installed, run the software, selected the card letter in Options, made Add and added some .gba and .nds
the gba opens fine (i don't press START, i select them and press A, they open anyway :) )
the nds don't open

one detail i've noticed is when i open a .gba it appers on screen loading the screen until the total (8mb for example, 500kb... 1000kb... 1250kb... and on) and opens the game
when i open a .nds it doesn't appears loading the total...

no doubt, i can't run any game, only the two demos...

even this homebrew:
