problem with DS Super card

I have i Nds but i don't have enough money to buy a R4. Then my friend gave m his Super Car mini, it's for GBA.
I still can play Nds games with it. But some games don't work well, like Lunar Knights or Castle Vania: Portrait of Ruin. Could you help me?

the supercard may simply not be fast enough. I know for a fact that Castlevania PoR will not run on an american micro SD card, because its simply not fast enough.if the supercard uses a micro SD, try using a faster card.sorry if this didn't helpyour welcome if it did

thanks, but the some other games don't work too, in fact, most of the game with ID 1000+ won't work, can some body help me out

and more game like Final Fantasy(U) version, Star Wars - Lethal Alliance, Megaman Zx and more
help me, please. I need your help. And i use a Super card on original DS not DS Lite, so it use Mini SD

try updating your firmware

How can i ugrade my firmware, please tell me guy

Google supercard, and read through their forums. Not all games work with the same settings in the convertor. And some don't work at all until they release an update. As someone said above some of the games will not run at full speed or at all with a standard card and require a high speed card. Whatever the problem your first stop should be the supercard forum. And I guarantee there will already be a thread with a solution about the game you are having problems with.

I ugrade my firmware but when i plai Final Fantasy III or Star War-Lethal Alliance, or Pokemon Diamond/Pearl the screen just go white, do you now why?

buy something proper then. try that m3ds simply or something built to play them.

Sorry guy, is may fault. Instead of copy firmware 1.83 to may Super Card, i copy firmware 1.60. Sorry guy, and thank you very much.
P/S:I have solved may problem(hope may grammar are ok)
