If you aren't doing any ROM hacking, you don't need to concern yourself with TBL files. If you are, though, you might want to use some of the ones we have to see how they work.
 Newlines and block end
The special codes *xx and /xx signal newline and end of block — or the other way around. It depends on the editor you're using. Translhextion, for example, uses * as newline and / for end of block, and WindHex has them the other way around. We don't really standardize on any particular tool, so any given TBL file may use either convention. Basically, just try dumping the text and reverse 'em if it looks like they're mixed up.
