Help if you can please

I am having big problems with some of the games and I am pulling my hair out over it!I am downloading games for my kids to play on a gameboy DS with an M3 Simply card.The games they want to play are--Kingdom Hearts (the new one)
--Mario and Sonic at winter olyimpics
--marion and luigi Bowers story
--Dora the explorer winter princessI cannot get these games to work on my card and it keeps freezing. I have looked all over your forum help pages and I cannot find the solution. I know I need a agame patch to make some of them work (before today I had no idea what this meant) so I've learnt something, but the instructions I found on the forum don't make it work on the game boy DS. Can you pleease offer me help so I can get these games working as I am now at a complete loss!If you could give me a link to a game that woks on M3 Simply that would be great, if not the patch site I downloaded won't let me follow the instructions you have already given (says invalid code) so please don't cut and past that from hereMany
thanksChris Norgate

I had tried this already! I had read through this early on in my search for the games but as I said these never worked and as such the M3 Simply won't play them.I'm looking for a set of guidelines that will work rather than a post of something i have already seen and tried.If there is anyone out there I'll really appreceiate it!Many thanks

Have you ask the people on that thread ?
At least those guys might be able to explain and show the right guidelines for it.
Try asking there.
