Cart DB #231: 4 in 1

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
