Software

The 1050 in 1 rom contains 3 MB of PRG and no CHR.

The rom has been assigned to the submapper 1 of the NES 2.0 Mapper 354.

It contains 80 different games that can be beginned at different levels.

N°	Game Name	Original Game Name	Level
1	NORTHERN KEN II	Hokuto No Ken II	Level 1

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) :

dump310331C-32-NRS.lua

This short-circuit in place, this script can dump the cartridge with the INLretro dumper :

local dump32_310331C = {} -- 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" -- file constants & variables local mapname = "unusabledump" -- local functions local function create_header( file, prgKB, chrKB ) nes.write_header( file, prgKB, 0, op_buffer[mapname], mirroring) end --dump the PRG ROM local function dump_prgrom( file, rom_size_KB, debug ) local KB_per_read = 32 local num_reads = rom_size_KB / KB_per_read local read_count = 0 local addr_base = 0x08 -- $8000 while ( read_count < num_reads ) do if debug then print( "dump PRG part ", read_count, " of ", num_reads) end -- hardware: A0-A2, D0-D2, D7 all go to PAL, which then generates A13-A16 -- A3 controls whether CHR RAM is writeable -- D6 specifies H/V mirroring control -- A4,A12 are A20,A21 -- D3-D5 are A17-A19 local datapart = (read_count & 0x1F) << 1; local addrpart = 0xE000 | ((read_count >> 1) & 0x10) | ((read_count << 6) & 0x1000); --select desired bank(s) to dump dict.nes("NES_CPU_WR", addrpart, datapart) --32KB @ CPU $8000 dump.dumptofile( file, KB_per_read, addr_base, "NESCPU_4KB", false ) read_count = read_count + 1 end end --Cart should be in reset state upon calling this function --this function processes all user requests for this specific board/mapper --local function process( test, read, erase, program, verify, dumpfile, flashfile, verifyfile) local function process(process_opts, console_opts) local test = process_opts["test"] local read = process_opts["read"] local erase = process_opts["erase"] local program = process_opts["program"] local verify = process_opts["verify"] local dumpfile = process_opts["dump_filename"] local flashfile = process_opts["flash_filename"] local verifyfile = process_opts["verify_filename"] local rv = nil local file local prg_size = console_opts["prg_rom_size_kb"] local chr_size = console_opts["chr_rom_size_kb"] local wram_size = console_opts["wram_size_kb"] --initialize device i/o for NES dict.io("IO_RESET") dict.io("NES_INIT") --dump the cart to dumpfile if read then print("\nDumping PRG-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_prgrom(file, prg_size, false) time.report(prg_size) --close file assert(file:close()) print("DONE Dumping PRG-ROM") end dict.io("IO_RESET") end -- functions other modules are able to call dump32_310331C.process = process -- return the module's table return dump32_310331C

NB : As it is a programmable chip, the behavior of the TIBPAL16L8 chip has needed to be understand before writing this dumping script.

Under UNIX, the commands to run are :

./inlretro -s scripts/inlretro3.lua -c NES -m dump310331c -x 4096 -d 1050in1_PRG_4096kb.nes

cp 1050in1_PRG_4096kb.nes 1050in1_PRG_3072kb.nes

truncate -s 3145744 1050in1_PRG_3072kb.nes

NB : For the truncate : 16 B (header) + 3 MB (3072 x 1024) = 3145744 bytes

The NES header of the rom is to set to

4E 45 53 1A C0 00 20 68 11 00 00 07 00 00 00 2A
