I'm bias towards any card OTHER than ak2i (use to be DSTTi - Didn't like the firmware but loved it with Moonshell as the filelauncher, but now the M3i0)
The Reason(s)
- I found AK2i SAV files are weird !!!
I am unable to use them with a few of my PC game editors (Animal Crossing is one of them), I can't even convert them using Shuny's website. Even Shuny found them 'weird' when I contacted him about it
- I have had SAV files corrupted by the Ak2i (& that was with AKAIO firmware)
- I've had Boot problems with the Ak2i locking up on the health screen - not only on a DSLite but also on a DSi (even with the 'piece-of-card' trick)
- The Ak2i 'locked-up' occasionally while playing games
- I had no support from the manufacturer's.
I contacted them about the problems I was having, they replied with 'Send us photos of your card with Name/Address/Email & We'll send you a replacement' & it never turned up - even when I re-contacted them 30days later to inquire where it was, I got no further replies
With other cards (even a 'clone' N5) I have had no problems at all with anything other than 'How do I get ... (Homebrew) to work'
