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
