First of all, I don't know if this question goes in this forum. After talking with a friend, and seeing DS Linux in action, we wondered if it's possible that a keyboard add-on would be used in the GBA Slot. It was a lot of speculation of course, since either of us knows well the DS hardware. We speculated that the GBA Slot is mainly an storage device, which is used mainly for reading. What if in this slot you can receive input signals which alter a certain data structure, which only detects changes on keys. Meanwhile, in slot 1 is running a program which every amount of miliseconds check for changes in the data structure, and this way simulate reading data from a keyboard. This idea assumes the DS can multitask processes of course, but in theory, DS Linux would allow that. Again, maybe this was a pipe dream Dilbert-boss-style, and we assume that if this is possible someone would have thought of that before, but we are curious for the reasons of why this is not possible. Thanx in advance.
