so did the test for derby stallion and it appears that single byte characters can be read so at least now you know that (if you do not have it get the unregisterable version of CT2 from march of 2009 and give it a try) both the full width and half width appear so translating this rom will actually be quite easy
and for a starter project actually pretty good (my starter was 7thdragon, still worKing on it)
So you know how to find the text and to dump the text (in extractors/inserters you just input the offsets and do what needs to be done, this does mean though that you might need to rework the pointers and that is another topic okay)
if your serious about translating a particular rom try to post a topic here ie Derby stallionDS translation project - if it looks like you will need a team or help if anyone is interested in helping you they will post in that topic (I felt and still feel that you should only post if you need help or you have a patch ready to hand out)
If you are having trouble finding a hexeditor try looking on romhacking.net
the free hexeditors there make you really appreciate crystaltlie2 (no offence to the authors of those hex editors alright, but a built in table file system and a kick butt searcher, tile viewer, plus inserter extractor, etc built into one... sigh)
