I got a bunch of non-working, mostly non-glob bootleg carts. For most of them dirty connector or bended legs that cause short-circuit were reason for non-work, but for some of them problems were quite more interesting, like broken chip or broken traces.
Anyway, some of the PCB are quite interesting (rare mappers) so I publish all photos/schemes, maybe some wiki articles can be updated.

FC01
Mapper: http://wiki.nesdev.com/w/index.php/INES_Mapper_087
Game: Ninja Jajamaru Kun (J)
Comments:
*CHR-ROM was missing so I had to write small program that compared PRG memory agains every known game from database (CRC/byte to byte comparision is not enough as many games are less or more hacked, so the one with least different bytes is taken)
*PRG ROM is quite weird (UMUA195) and looks like it is EPROM with window covered by epoxy. For some u
*There is some weird connection between 74*139 pins 12 & 4 (protection?)

FC04
Mapper: NROM
Game: Magmax (J)
Comments: This blue laminate is really weird (it is not blue paint)
Image Image
---------------------------------------------------------------------------------------------------------------------
FC05
Mapper: CNROM
Game: Hokuto no Ken (J) [a1]
Comments: Bootleg CNROM game, no protection diodes were added
Image Image
---------------------------------------------------------------------------------------------------------------------
FC06
Mapper: NROM
Game: Sky Destroyer (J)
Comments: Both PRG & CHR has uncovered eprom window, so its content was destroyed. I had to find what was the game by finding most similar ROM sets. Interestingly, the PCB is exactly the same like previous one, but without 74161 soldered in.

---------------------------------------------------------------------------------------------------------------------
FC07
Mapper: UNROM
Game: Ninja Kun - Ashura no Shou (J).nes
Comments: Roms are placed on the back side, just like in FC carts
Image Image
---------------------------------------------------------------------------------------------------------------------
FC08
Chips:
Mapper: MMC1
Game: Rockman 2 - Dr Wily no Nazo (J)
Comments: 256kB MMC1 game, but ROM is divided into two 128 kB chips. Also, the MMC1 [KS 203] has non-standard pinout and it has external reset line!
Problems: ROM1 has broken content & RC contant in MMC1 caused staying in reset for too long.

FC09
Game: Bio Miracle Bokutte Upa (AKA Mario Baby) (Chinese)
Mapper: http://wiki.nesdev.com/w/index.php/INES_Mapper_042
Comments: 4071 was broken and needed to be replaced
Image Image Image
---------------------------------------------------------------------------------------------------------------------
FC10
Mapper: custom
Game: Teenage Mutant Ninja Turtles (J)
Comments: Another game ported to VRC2 + additional circuit for IRQ generation (this time from MMC3)
Image Image Image Image
---------------------------------------------------------------------------------------------------------------------
FC11
Mapper: CNROM
Game: Gradius (J)
Comments: PRG chip was broken, fortunatelly there were solder pad around so 64 kB PLCC32 flash was soldered.
Image Image Image
---------------------------------------------------------------------------------------------------------------------
FC12
Mapper: MMC1
Game: Saint Seiya - Ougon Densetsu Kanketsu Hen (J)
Comments: 2x64 kB PRG chips & 2x64 kB CHR. Unfortunatelly MMC1 (standard pinout, without any markings) chip was broken and CHR D1 & CHR D2 traces was broken. Game wont load if CHR lines are not working properly.
There are some funny jumpers on the PCB which allows also for soldering one DIp28 128 kB as PRG/CHR.

Image Image Image Image
---------------------------------------------------------------------------------------------------------------------
FC13
Mapper: MMC1
Game: Silk Worm (U), Chip to Dale no Dai Sakusen (J), Guevara (J), TaleSpin (U)
Comments: 4-in-1 MMC1 games, reset based cartridge, MMC1 standard pinout (AX5904)
Image Image Image Image
---------------------------------------------------------------------------------------------------------------------
FC14
Mapper: MMC3
Game: Rockman 5 [Darkwing Duck hack], 8 in 1 GETOUT [Datsugoku (CTC Pirate) (J)]
Comments: 2-in1 MMC1 games, reset based
Image Image
---------------------------------------------------------------------------------------------------------------------
FC15
Mapper: 80
Game: Kyonshiizu 2 (J)
Comments: X1-005
Image Image
There are remains of battery socket but this game does not use battery (?)
---------------------------------------------------------------------------------------------------------------------
FC16
Mapper: custom
Game: 190-in-1
Comments: This is exactly the same like http://wiki.nesdev.com/w/index.php/Rinc ... _cartridge, but without the PRG-ROM patch (and PAL for enabling it).
Image Image
---------------------------------------------------------------------------------------------------------------------
FC17
Mapper: MMC3
Game: 4-in-1 MMC3 gamees (Super Fighter III, Turtles, Boukenjima 3, Chip and Dale)
Image Image
---------------------------------------------------------------------------------------------------------------------
FC18
Mapper: VRC4
Game: Moe Pro! - Saikyou Hen (J) [hM23][p1]
Comments: Original game (on JALECO mapper) probably uses additional effect chip. This one does not, but there is resistor between sound from CPU and to rca connector, probably for volume control.
Image Image
Unfortunatelly PRG memory is broken.
---------------------------------------------------------------------------------------------------------------------
FC19
Mapper: 94
Game: Senjou no Ookami (J)
Comments: UNROM pcb (with 4x32 kb) and D0-D2 lines changed into D2-D4
Image Image
---------------------------------------------------------------------------------------------------------------------
FC20
Mapper: VRC4
Game: Teenage Mutant Ninja Turtles (J)
Comments: VRC2 + external IRQ circuitry
Image Image Image Image
---------------------------------------------------------------------------------------------------------------------

Mmm, much closer to Namco 175 (i.e. mapper 210) instead of Namco 163.

The discrete logic implementation here is the same for the eight registers from $8000 through $BFFF (i.e. CHR banking) and the three registers from $E000-$F7FF (i.e. PRG banking) but nothing guarantees that the last bank is fixed to the last bank as Namco's hardware does. So the 74'670s must (again) power up containing $F, and whatever initialization of the 163's sound hardware (which the game doesn't use otherwise) must have been dummied out.

FC21 was likely manufactured by Ka Sheng if you're wondering. That's their typical PCB code.
