I just released a bit of e-reader information too, including a dotcode
printing tool (some ppl already have it), more to follow soon...

http://www.alpha-ii.com/caitsith2/ereader/dot-code%20block.jpg - explanation
on how the raw data is stored in the dotcode blocks in the strip.
Now, the only thing that is really stopping us from
developing our own dotcodes, is the fact that we do not know how to
encode/decode the nintendo specific reed-solomon codes.
essentially, it goes like this.
Binary data + reed-solomon codes = Raw data. (unsolved)
Raw data + 8/10 Modulation = Dotcode dots. (solved)
It would be helpful to know where the e-reader functions are, in the rom,
and what each of them does. maybe we can reverse engineer the reed-solomon
encoding/decoding out of one of the functions.
