INES Mapper 036
- Strike Wolf (also released as Comando de Lobos)
Even though these games can evidently be emulated as a weird kind of GNROM, the hardware does something quite different:
The CHR banking is definitely implemented using the two 7400-series ICs:
Mask: $E200 write $4200: [.... CCCC] - Select 8 KiB CHR bank
The PRG banking is part of the ASIC:
Mask: $E103 read $4100-4103: [xxRR xxxx] |||| |||| ||++------ Copy internal register 'RR' to data bus. ++---++++- open bus write $4100: when M=0, copy internal register 'PP' to internal register 'RR'. When M=1, RR=RR+1 write $4101: no visible effect write $4102: [..PP ....] - Copy data bus to internal register 'PP'. Value is not yet exposed anywhere. write $4103: [...M ....] - PRG banking mode (0: copy, 1: increment) write $8000-$FFFF: copy internal register 'RR' to PRG banking pins
This PRG behavior is confusing but seems to be complete.
The 05-00002-010 ASIC is connected as:
.--\/--. ¹NC <- |01 24| -> NC¹ (r) PRG A16 <- |02 23| -> NC² (r) PRG A15 <- |03 22| -> NC³ GND ?? |04 21| <- CPU A13 (rn) 5V ?? |05 20| <- CPU A14 (rn) ²NC <> |06 19| ?? GND 5V ?? |07 18| <- CPU R/W (n) ²NC <> |08 17| <- /ROMSEL (rn) ²NC <> |09 16| <- M2 (n) ¹NC <> |10 15| <- CPU A8 (rn) (rn) CPU D5 <> |11 14| <- CPU A1 (rn) (rn) CPU D4 <> |12 13| <- CPU A0 (rn) '------' ¹: pins 1, 10, and 24 could respectively function as PRG A17, CPU D6, and PRG A18 if they were connected. PRG A18 can only be toggled, and that only by using the increment behavior ²: pins 6,8,9, and 23 could respectively function as CPU D0, D1, D2, and CHR A13 if they were connected; however writes to $4101 then cause extra obfuscatory behavior ³: Defective, always high
Three additional games published by Gluk use the same PCB, with no ASIC. They were also released in other regions on different hardware, and only Gluk's editions are compatible with the above-mentioned CHR banking.
- F-15 City War
- Volley ball
Compatibility code left in means that all editions of these three games are emulatable as NINA-06.
