Static, disc-only probe for why a .slb bank's XMA1 stream starts at 1392 / 1468 / 1600 / 1728 bytes in. Subcommands: phases the sound.p00..p04 size table and the running sums mod 2048 verify predicted vs measured offset over every bank on the disc bank structural dump of one entry (bank headers, waves, seek chunks) chain the tiling arithmetic across consecutive entries Reads nothing but dat/sound.pak, dat/sound.p00..p04 and tables.pak.
