Cart DB #56: Batman (TTL)

Notes for chip search:

Use "+" as delimeter for all fields (except "cart name", where space is used); if many values are entered, all of them must appear in the cartridge then; case is not sensitive
"Mapper" is the actual mapper used by this cartridge hardware (might not match the one at wiki.nesdev.com, as at the moment I was analyzing this cartridge, there was no mapper assigned to it, so I had to assign my own number for testing)
"Original mapper" is the mapper used by licensed version of this game (for multicarts, it refers to mapper of the inside games, so 0+2 means this cartridge can run NROM+UNROM games)
Order in which you put values doesn't matter (you can write 7400+74138+7400 or 7400+7400+74138 to search for a cartridge that contains at least two 7400 chips and one 74138
Some chips (like PAL16*8) appear in cartridges as 16V8 or 16L8, so be sure to check both posibilities
Same goes for memories - type 27F080 to search for 32 pin memories, 27512 for 28 pin with two chip enables or MASKROM_1M_DIP28 for 28 pin with one chip enable
Same goes for mappers - some examples: AX5904(MMC1), AX5202P(MMC3), PT8154BM (9112MMC3), AX5208C(VRC4), 23C3662(VRC2)
Good news is that you can use wildcards, so 74139+*MMC3* will search for any cartrige that has at least one 74139 and MMC3 chip in any version

Pirate FME7 [[File:Pirate FME7 components.jpg|thumb]] [[File:Pirate FME7 front.jpg|thumb]] [[File:Pirate FME7 back.jpg|thumb]] [[File:Pirate FME7 scheme.png|thumb]] This Pirate FME7 (used at least for game Batman, which has identical PRG & CHR compared to licensed version) is built entirely using discrete chips with addition of one PAL16L8 for generating clocks and enable signals. It is almost the same like original [[Sunsoft FME-7|FME7]] with the following exceptions: *max PRG-ROM 128 kB (but can be increased up to 4MBit by adding one 74*670), *hardwired vertical mirroring, *no WRAM at $6000-$7fff but PRG-ROM, *IRQ enable & IRQ counter enable combined into one bit. =Capabilities= *PRG-ROM: 128 kB *CHR-ROM: 256 kB) *Bus conflicts: no *Mirroring: vertical (hardwired) *One presettable 16 bit counter which decreases at beginning of cpu cycle (rising edge of M2) and triggers interrupt when decreasing from $0000 to $ffff =Memory map= *CPU $6000-$7fff: 8kB switchable PRG bank *CPU $8000-$9fff: 8kB switchable PRG bank *CPU $a000-$bfff: 8kB switchable PRG bank *CPU $c000-$dfff: 8kB switchable PRG bank *CPU $e000-$afff: 8kB PRG bank, fixed to the last bank *PPU $0000-$03ff: 1kB switchable CHR bank *PPU $0400-$07ff: 1kB switchable CHR bank *PPU $0800-$0bff: 1kB switchable CHR bank *PPU $0c00-$0fff: 1kB switchable CHR bank *PPU $1000-$13ff: 1kB switchable CHR bank *PPU $1400-$17ff: 1kB switchable CHR bank *PPU $1800-$1bff: 1kB switchable CHR bank *PPU $1c00-$1fff: 1kB switchable CHR bank =Registers= ==Register select== [....
