more e-reader info at http://www.alpha-ii.com/caitsith2/ereader

the released bin/raw data of the e-reader cards might cause controversy, but
at the same time, the items these cards unlock, can also be unlocked with an
action replay, and the bin/raw data is very similar, that it might help
with the reed-solomon code cracking. (heck, the dotcodes on the actual
powerup cards look very similar, with only a few bytes in the bin data, and
maybe 20-60 bytes in the raw data being different.)
