Here are Disch's original notes:
========================
= Mapper 077 =
========================
Example Game:
--------------------------
Napoleon Senki
Notes:
---------------------------
This mapper has 4-screen mirroring!
Also, it has 8k CHR-RAM in addition to any CHR-ROM present.
I'm unsure whether or not this mapper suffers from bus conflicts. Use caution!
Registers:
---------------------------
$8000-FFFF: [CCCC PPPP]
C = CHR Reg (2k @ $0000)
P = PRG Reg (32k @ $8000)
CHR Setup:
---------------------------
CHR-RAM is fixed at $0800-$1FFF. CHR-ROM is swappable at $0000:
$0000 $0400 $0800 $0C00 $1000 $1400 $1800 $1C00
+---------------+---------------+---------------+---------------+
| $8000,ROM | {0},RAM | {1},RAM | {2},RAM |
+---------------+---------------+---------------+---------------+
