Software

The 50 in 1 rom contains 64 KB of PRG and 32 KB of CHR.

The rom has been dumped and assigned to the INES Mapper 200.

It contains 4 different games that can be beginned at different levels.

Dumping method

This script can dump the cartridge with the INLretro-prog dumper (Device firmware version: 2.3.x) :

dumpMG109.lua
File:DumpMG109.lua.txt 
-- create the module's table
local dumpmg109 = {}

-- 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 : 200 ; Mirroring : 0 (Horizontal)

	nes.write_header( file, prgKB, chrKB, 200, 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

		local nobusconflicts = dict.nes("NES_CPU_RD", 0x8000 | read_count);
		dict.nes("NES_CPU_WR", 0x8000 | read_count , nobusconflicts)

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

		read_count = read_count + 1
	end
end

--dump the CHR ROM
local function dump_chrrom( file, rom_size_KB, debug )

	local KB_per_read = 8	--dump both PT at once
	local num_reads = rom_size_KB / KB_per_read
	local read_count = 0
	local addr_base = 0x00	-- $0000


print("PPU dump :")

	while ( read_count < num_reads ) do

		if debug then print( "dump CHR part ", read_count, " of ", num_reads) end

		local time=os.clock()+1
		while time>os.clock()
			do
			end

		local nobusconflicts = dict.nes("NES_CPU_RD", 0x8000 | read_count);
		dict.nes("NES_CPU_WR", 0x8000 | read_count , nobusconflicts)

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

		read_count = read_count + 1
	end
end

-- return the module's table
return dumpmg109

Under UNIX, the commands to run are : 

./inlretro -s scripts/inlretro3.lua -c NES -m dumpmg109 -x 64 -y 32 -d 50in1-1993.nes
