The CHR part is a RAM chip, so it doesn't contain any datas to dump.

Software

The 120 in 1 rom contains 512 KB of PRG and no CHR.

The rom has been dumped and assigned to the submapper 1 of the INES Mapper 227 on the 25 march 2023.

It contains 13 different games that can be beginned at different levels.

The rom is fully supported from FCEUX 2.6.6.

Dumping method

For dumping this cartridge, it's necessary to short-circuit this capacitor (by putting an electric wire between its two pins) :

Capacitor to short

This short-circuit in place, this script can dump the cartridge with the INLretro-prog dumper (Device firmware version: 2.3.x) :

dumpN120_72.lua
File:DumpN120 72.lua.txt 
-- create the module's table
local dumpn120_72 = {}

-- import required modules
local dict = require "scripts.app.dict"
local nes = require "scripts.app.nes"
local dump = require "scripts.app.dump"
local flash = require "scripts.app.flash"
local time = require "scripts.app.time"
local files = require "scripts.app.files"
local swim = require "scripts.app.swim"
local buffers = require "scripts.app.buffers"


-- local functions
local function create_header( file, prgKB, chrKB )
	-- Mapper : 227 ; Mirroring : 0 (Horizontal)

	nes.write_header( file, prgKB, chrKB, 227, 0)
end

--dump the PRG ROM
local function dump_prgrom( file, rom_size_KB, debug )

	--PRG-ROM dump 16KB at a time
	local KB_per_read = 16
	local num_reads = rom_size_KB / KB_per_read
	local read_count = 0
	local addr_base = 0x80	-- $8000

print("CPU dump :")

	while ( read_count < num_reads )
	do
		if debug then print( "dump PRG part ", read_count, " of ", num_reads) end

		-- pause of 1 second to take care about the chips
		local time=os.clock()+1
		while time>os.clock()
			do
			end

		dict.nes("NES_CPU_WR", 0x8000 | ((read_count & 0x1f) << 2) | ((read_count << 3) & (1 << 8)) , read_count)

		dump.dumptofile( file, KB_per_read, addr_base, "NESCPU_PAGE", false )

		read_count = read_count + 1
	end
end

--Cart should be in reset state upon calling this function

	local wram_size = console_opts["wram_size_kb"]

--initialize device i/o for NES
	dict.io("IO_RESET")
	dict.io("NES_INIT")

print("\nRunning dumpN120_72.lua")

--dump the cart to dumpfile
	if read then
		print("\nDumping ROM...")

		file = assert(io.open(dumpfile, "wb"))

		--create header: pass open & empty file & rom sizes
		create_header(file, prg_size, chr_size)

		--TODO find bank table to avoid bus conflicts!
		--dump cart into file
		time.start()

		--dump cart into file
		dump_prgrom(file, prg_size, false)

		time.report(prg_size)

		--close file
		assert(file:close())

	end

	dict.io("IO_RESET")
end

-- functions other modules are able to call
dumpn120_72.process = process

-- return the module's table
return dumpn120_72

Under UNIX, the commands to run are : 

./inlretro -s scripts/inlretro3.lua -c NES -m dumpn120_72 -x 512 -d 120in1-contra-1992.nes


The NES header of the rom is to set to : 

4E 45 53 1A 20 00 30 E8 10 00 00 00 00 00 00 00
