With these types, there should be +one text for the disc and one for each track. +With types 0x88 and 0x89, the second byte bears a track number, too. +With type 0x8f, the second byte counts the record parts from 0 to 2. + +The third byte is a sequential counter. + +The fourth byte is the Block Number and Character Position Indicator. +It consists of three bit fields: + bit7 = Double Bytes Character Code (0= single byte characters) + bit4-6 = Block Number (groups text packs in language blocks) + bit0-3 = Character position. Either the number of characters which + the current text inherited from the previous pack, or + 15 if the current text started before the previous pack. + +The 12 payload bytes contain pieces of 0-terminated texts or binary data. +A text may span over several packs.
