Re: Decoding JBK 6628 DVD Karaoke Disc

Patching findings:

Song 1:
1074: 54 -> 53 ->> changes all T in the song to S
1c70: 06 -> 05 ->> the music is messed up (wrong instruments?)

Song 3538:
3f5b5ba: 77 -> 78 ->> no noticable effects
3f5b5e1: 53 -> 52 ->> no noticable effects
toward end of block ->> stop the music early

The first part of the block look like some sort of lookup table for the lyric.  If I could patch to change one letter of the lyric, that would give a very big clue.
