Hi all. I have recently purchased my first flash cart for my DSi (running firmware version 1.4.1A), an M3i Zero. It's running the version 1.49 M3 Sakura, and works great; but only when it works. The problem that I face is even though the DSi recognises the cart perfectly fine, i.e. showing the "Alex Rider Stormbreaker THQ" title, it sometimes just shows a black screen or the message 'No SD card found' when i tap it. The odd thing is that without touching the cart or the SDHC card, it shows both the black screen or the message interchangeably each time i reset and startup the cart. When it finally manages to startup though, the whole Sakura system works smoothly. I'm very sure my 4GB SanDisk MicroSDHC is in perfect working order, formatted to FAT32 file system. So I'm just wondering what could be the problem? I hope I don't have to buy a new cart because of this problem because it's my first cart and I've only used it for less than a month!
