Can you help getting more info about those carts?
Cart name
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

Extra info:
* This cartridge was not working properly - selecfing any game except the first one caused it to restart itself instead of loading game.
* Reason for that behaviour was lack of any capacitor in the reset detecting circuit
* There is a place to connect cap to GND (C9) but it should be connected to VCC instead (C1)
* There is also a cut trace that is fixed again by wire that selects the address at which the outer register is enabled
(track cut = $5000 / track fixed = $5800);
* Dumping this cartridge was hard as sometimes writes to the $5800 did not cause proper value to be latched - reason for that was
that 74138 does not have M2 routed, also dumpers keep cpu address bus unchanged after write cycle, so that the only thing that clocked 74138 is the CPU R/W line, which should rise BEFORE change of CPU Data bus in order for it to work properly
* And of course the menu code starts writing to PPU without waiting one frame, which causes menu to look glitched
