dumb security check, decompressing a single string.

Each channel appears to be connected to a different set of ROMs, however there is

defintiely only 315-5838 single chip.

defintiely only a single 315-5838 chip. (could the different channels actually just
|

be mirror addresses, with part of the address determining the ROMs to use?)

|

Dead of Alive only uses a single channel, and has the source data in RAM, not ROM.
|

This is similar to how some 5881 games were set up, with the ST-V versions decrypting
