NES 2.0 Mapper 358 denotes a variation of NES 2.0 Mapper 282 with partially overlapping PRG/CHR outer banks:
- 1997 Super Game 7-in-1 (JY-016) (PCB YY860606C, 512 kiB PRG-ROM)
- 1998 Super HiK 5-in-1 (JY-113) (PCB YY860606C, 512 kiB PRG-ROM)
- 1998 Super HiK 6-in-1 (JY-117) (unmarked PCB, 1024 KiB PRG-ROM)
Outer Bank Register ($D003)
Mask: $F803
7654 3210
---- ----
..M. .ppC
| ||+-- CHR-ROM A18 if M=0, ignored if M=1
| ++--- PRG-ROM A18-A19
| +---- CHR-ROM A19
+-------- Outer CHR bank size and selection
0: Mask to 256 KiB, use C
1: Mask to 512 KiB, ignore C
PRG ($8000-$8FFF) bank select register bits that select 256 KiB banks are masked off. Dumping the CHR-ROM does not work reliably in 1 KiB CHR-ROM banking mode.
