 Example Games:
 --------------------------
 Jing Ke Xin Zhuan
 Sheng Huo Lie Zhuan
 
 
 Registers:
 --------------------------
   $4020-5FFF:  [PPPP CCCC]
     P = Selects 32k PRG @ $8000
     C = Selects 8k CHR @ $0000

This is two similar PCBs with subtly different addresses for the register.

Jing Ke Xin Zhuan (荊軻新傳) decodes the register as: (ADDRESS & $E800) == $4800 Sheng Huo Lie Zhuan (聖火列傳) decodes the register as: (ADDRESS & $E100) == $4100

Both boards add PRG RAM at the usual $6000
