When you say "2MBIT FLASH", you mean the original DS cart that I have in the PassMe? If so, which new ones are 2mb?
Nintendogs has a 2mbit save.
I'm in the same boat as you, I can't play it because I don't have an original game with a 2mbit save
Turns out Nintendogs: Best Friends was 2MBIT after all.
Rocking out on my NeoFlash.
