Please help,m3 ds real sakura wont play on my ds lite

Hello everyone,I'm having problems getting my m3 ds real sakura to work on my new ds lite.It should goto the load screen when i turn on the ds,but it goes to the regular ds screen and it says there is no game pack inserted.i have no idea whats wrong.If you have any solutions please let me know,thank you in advance ;)

do any other games load? maybe your card reader is dead

it does play ds games,but it just wont play the M3,i was wondering if i need to get a game cartridge other than a M3,like the R4.or is there a simpler solution to my problem that im just not seeing

I have an M3 Real, and sometimes, for no reason, it does that. What I do is take the cartridge out, remove the micro SD, blow in that slot, blow both sides of the micro SD, then blow the metal touches on the cartridge, and finally give the DS slot a good, short blow. Plug it in, and it should work. Hope this helps!
