Over at a Chinese forum, a forum manager got his hands on the upcoming M3 Lite for the Nintendo DS Lite. The M3 Lite will allow users to run homebrew and other .nds files straight from their MicroSD memory card assuming they have a no-pass device such as the Passcard 3 and this product.
We've seen several revolutionary flashcarts this year including this product. This is the summer of flashcarts, and all have their own pros and cons. The M3 Lite however, has numerous pros and only a few cons. One of the only cons that I can think of without having the product in my hands (yet), is the expensive price of 79.99$, but this is all worth it in the end as MicroSD cards only range in the 20$-50$ range for high capacities (512mb - 1gb). This is the first flush-fit adapter from M3 even after they released several versions such as the CF, SD, Slim SD, and MiniSD adapters.
