Ok, I'm really new to the DS Homebrew scene (I'm coming from the PSP scene) and I'd like to know:
1: What is a good, single card (aka one piece) easy to use, flashcart that can play DS and GBA backups? Also, since it would be on a new DS Lite, it would need to work on all firmwares.
2: What size is the average DS backup?
3: What is the most reliable, cheapest place to get flashcarts.
