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
