Cart DB #14: 11 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

2021-07-12 email=huu huynh [huuan.huynh87@gmail.com] rom Hello. 1) There has been some flooding attack on the nesdev forum by stupid russian idiots. As a result, the database of forum became broken (some users were accidentally deleted by that). They're working on restoring it. 2) This cartridge is quite interesting. First, because it consists of 2xUNROM + NROM games. Second, because the mapper is inside black epoxy blob (which is rather unusual for UNROM+NROM multicarts). Third, because the 74157 chip is responsible for switching what is wired to PRG-A[3..0] lines (there are some cut traces underneath). As a result, depening on those "hardwired jumpers", game can display one of sixteen different version of menus (the missing 7402 chip could also alter the PRG-A[4] line in same way, which would expand the number of menus from sixteen to thirty two) 11 in 1 42 in 1 118 in 1 120 in 1 150 in 1 168 in 1 <- this is yours 188 in 1 190 in 1 52 in 1 64 in 1 66 in 1 82 in 1 100 in 1 136 in 1 266 in 1 288 in 1 3) I analyzed the PCB and the mapper takes use of cpu lines A14, A9..A0 (and only that). So this is simple address-latch mapper. This is again interesting, because UNROM games (like Contra, Side Pocket) need access to CPU-D[2..0]. So they were patched on this multicart to use address bit, instead of data bits. It would be hard to guess how this mapper works but I managed to analyze CPU writes on each menu entry selection and guessed which bit is responsible for: powerup: f004, f004, 901c, f100, 8004 Contra | | 128k | $F260 1111001001100000 Side Pocket | | 128k | $F240 1111001001000000 Tetris 2 | V | 32k |$8014 $8000 $F099 1111000010011001 Duck Hunt | V | 16k |$8010 $8000 $F0BC 1111000010111100 Wild Gunman | V | 16k |$8010 $8000 $F088 1111000010001000 Mahjong | V | 16k |$8038 $8000 $F0AC 1111000010101100 Mario | V | 32k |$8034 $8000 $F0A1 1111000010100001 Tank | H | 16k |$8014 $8000 $F08E 1111000010001110 Ice Climber | H | 16k |$8034 $8000 $F0AA 1111000010101010 Binary land | H | 16k |$8038 $8000 $F0B2 1111000010110010 Galaxian | H | 16k |$8004 $8000 $F002 1111000000000010 fe 9876543210 xayPPPPpmv |||||||||+-- Size (0=16k, 1=32k) ||||||||+--- Mirroring (0=V, 1=H) |||+++++---- PRG bank |+---------- PRG-A3..0: 0=CPU-A, 1=fixed at %0101) +-+--------- Mode (01=NROM, 10=UNROM with $c000 fixed to last, 00=UNROM with $c000 fixed to first) xy v $8000 $c000 10 * PPPPp PP111 00 * PPPPp pp000 *1 0 PPPPp PPPPp *1 1 PPPP0 PPPP1 4) I think this is mapper 227 in FCEUX (I attach rom with header and schematic of your cartridge)
