5
6   Package Type: TQFP100
7
8   This appears to be a dual channel compression chip, used in 1996, predating the 5881.
9   Decathlete uses it to compress ALL the game graphics, Dead or Alive uses it for a
10   dumb security check, decompressing a single string.
11
12   Dead of Alive only uses a single channel, and has the source data in RAM, not ROM.
13   This is similar to how some 5881 games were set up, with the ST-V versions decrypting
14   data directly from ROM and the Model 2 ones using a RAM source buffer.
