BadVaddr as the group starts: 00000480
Commands written while busy. Each row: a reset, 2000 cycles, a busy state, its status;
then four MDEC(0) markers 0000A001h-A004h (bits 0-15 show in the status when taken as a
command, commands.txt:33-37), or a decode command for C words (8 bit) and C FE00FE00h;
the status after each store, then 2000 cycles later.
A full luminance quant table (16 words):
  8004FFFF, markers: 8004A001 8004A002 8004A003 8004A004; later 8004A004

  8004FFFF, decode for 4: A2040003 A2040002 A2040001 A2040000 E204FFFF; later 8204FFFF
A full scale table (32 words):
  8004FFFF, markers: 8004A001 8004A002 8004A003 8004A004; later 8004A004

A scale table short by 1 (31 words):

An 8 bit decode for 4 words given 2:
  A2040001, markers: A2040000 E204FFFF E204FFFF E204FFFF; later 2204FFFF
  A2040001, decode for 1: A2040000 E204FFFF; later 2204FFFF
  A2040001, decode for 2: A2040000 E204FFFF E204FFFF; later 2204FFFF
  A2040001, decode for 4: A2040000 E204FFFF E204FFFF E204FFFF E204FFFF; later 2204FFFF
An 8 bit decode of the block, all 32 words in, output unread:
  2204FFFF, markers: 2204FFFF 2204FFFF 2204FFFF 2204FFFF; later 2204FFFF
