When I upgraded I found the problem wasn't with the card (I was using an M3)
but with the games. The newer games were using much better DRM protection, and games would either not work or crash after two minutes.

I swapped my card for an AceKard 2 and haven't had any problems with the DSi (which itself has now been upgraded to an XL - go, me!).

Alternatively, I would suggest going to the R4 website and finding a firmware update. If they are the ones telling you to get the next card up, then ask around on gamers' forums. Someone, somewhere, will have cracked the problem.

Having said that, I had to admit defeat before xmas and bought (well, got mr b3th to buy for my birthday) four actual games that I needed to play but couldn't get working. As these are the only genuine games I've bought in three years, I don't mind the expense...

How, exactly did you NEED to play these games?

as will many of the ways of women, Jeff
I bet you understand why my dog needs to play with squeaky toys though, right?
