Forgive me if this is a commonly asked question. I've tried browsing and searching but haven't found the info I'm looking for. I regularly browse the Wii Hacking forum and I've happily had homebrew running successfully on my Wii for many months now. I am a pretty technical person and have no problem reading lots of information to become knowledgeable about a topic. However I will likely be buying myself a Nintendo DS for X-mas. I've had a bit of trouble finding general information on how DS homebrew (and hacking) works. I would like to learn about these things and as I said I don't mind doing a lot of reading, I'm sure this has all been covered before. I have lots of basic questions that don't seem to be readily answered by any of the threads I've looked at in the DS section. I would have posted these questions in a 'General' section but I couldn't seem to find one. Does a DS require a modchip to run DS roms and other homebrew/emulators? If so, where can I find more information (reviews/comparisons)? I see a lot of information about flash cards, from what I've read it looks like ROMs are loaded onto flash cards that are then loaded on the DS. Where can I find more information about the basics of this process? I'd like to know about the differences between types of flash cards, circumstances for the use of flash cards, firmware modifications or anything DS hacking/homebrew related. If someone can point me to some threads covering these (and other beginner topics), that would be great.
