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 one is internesting. The equivalents of russian chips are:
KR1533LL1 = SN74ALS32
K555IE10 = 74LS161
K555LA3 = SN74LS00

But I don't see here enough logic to support this:
[code]
$8001, mask: f0001:
[.... ...m]
         +-- mirroring (0=V, 1=H)
		 
$9001, mask: $f001:
[.... PPP.]
      +++--- 16kB PRG bank at $8000
	  
$8000 | $ffff
------+-------
 PPP  |   7
[/code]

Maybe $8000 and $9001 are merged into one register (that would make sense because they use different data line.
* 4/4 of 7400 might be used for mirroring mux
* 3/4 of 7432 for OR-ing A14 with PRG-A14/15/16 for last bank.
* 1/4 of 7432 for ORing /ROMSEL and CPU-A14 to make the reg appear at $8000-$BFFF (?)

Note the unpopulated place for DIL14 chip.


Do you have back-side photo of this PCB?
