INES Mapper 036
iNES Mapper 036 is assigned to TXC's PCB 01-22000-400, featuring a 74138, a 74175, and usually a 24-pin ASIC labeled 05-00002-010. Two games are currently known to require this definition.
- 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: $E100 read $4100: [xxRR xxxx] |||| |||| ||++------ Copy internal register 'RR' to data bus. ++---++++- open bus Mask: $E103 write $4100: If Increment is set, internal register 'RR' <- 'RR'+1 Otherwise, if Invert is clear, copy internal register 'PP' to 'RR' if Invert is set, copy '~PP' to 'RR' write $4101: [...V ....] - Invert Mode write $4102: [..PP ....] - Copy data bus to internal register 'PP'. Value is not yet exposed anywhere. write $4103: [...C ....] - Increment Mode Mask: $8000 write $8000: copy internal register 'RR' to PRG banking pins
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 Gluk's editions of these three games are also emulatable as NINA-06.

- The same ASIC showed up in iNES Mapper 132 and iNES Mapper 173, wired differently.
