Slot 2 transfers data faster, and can play GBA games.
Most Slot 1 carts have better NDS compatibility and no need to flash your DS. I have never experienced slowdowns with my DS-X. I have read that the only slowdows from M3/R4 is when matched with below average SD cards.
GBA games need the faster data tranfer rate so if you want to have GBA games you need a slot 2. Otherwise Slot 1 is the way to go. The big Slot 1 carts have a passthru feature where if you want to run a slot 2 cart you can without flashing your DS.
On a sidenote. If you want to play wifi system link, DS-X is the best for that. It can link to a flashed or unflashed NDS.
Ahhh all confused.
So slot 2 is faster than slot 1. Slot 1 is better for DS compatibility. I would need a slot 2 device to play GBA games though. So if I buy a M3 Simply and then later decide "hey I want to play Super Pokemon Bowling Pinball Extreme GBA" I will need to buy a slot 2 device. These are basically the same as the slot 1 devices? You can have onboard flash or mini sd.
Flashing your DS. I guess this would be like soft modding your Xbox? I watched a video on you tube and the guy used some sort of DS card Passme or Passkey... I forget and he had to use a small metal contact to short out a jumper. What benefit does flashing allow? Or would the M3 Simply do the job fine?
Also can I play my backup roms online?
Oh and last question. Is there anyway to get rid of the safety screen on boot? lol
