Nes Multicart Famicom

[Nikolka]

Hello, I have a famicom multicart, the cards have new mappers. Can anyone decrypt? And share on yours site? I have a dumper.

Thanks for the feedback

Which multicart is it? Are you sure it has a new mapper? What you could do is get it looked at by someone skilled at dumping roms.

yes i am sure. they are not in the nesdev mapper table

Dragon2snow confirmed it

for example
Mapper NC-20MB
Mapper 8090
similar to mapper 395
and KD-7/9-c, HP898D,
NC-3000M

I have data from two multicart but no one knows what the mapper is, because it is new, there is no emulator for these mappers

[Nikolka]

I don't know who understands, I would like to share my multicart for other people

[NewRisingSun]

What dumping device do you have?

[Nikolka]

still this rom similar to the mapper 395 and 52.

[Nikolka]

i can also send a pcb

for all the multicart I've sent here

[NewRisingSun]

So you already have ROM files of them all, and just need them emulated? Or do you have completely undumped multicarts as well? Unfortuntely, I am not familiar at all with the syntax of the script you posted.

I have temporarily added support for what you set to mapper 108 as mapper 428. I need to check though whether one of the previous 400 already-assigned mappers could not take it.

These are mapper 319:

130-in-1
63-in-1 NJ-01b
66-in-1 KD-6130
78-in-1 KD-6129

Thank you. I thought so

unfortunately i can't dump, i don't have a scripting mapper 319, can you please help me?

This is a new mapper, I don't have data, just a menu listing 20 in 1

 PCB NC-20MB

As I said before, unfortunately, I cannot write scripts for your dumper, as I am unfamiliar with that syntax. Please ask someone like dragon2snow or byemu to write a script for mapper 319, using the information on Mapper 319's wiki page.

Edit:
I have added mapper 428 for KB46 and 14-in-1 to NintendulatorNRS.
160000 rawdata still confuses me.
6000-in-1 does not really seem to be mapper 227?

An "Anago Kazzo" script for mapper 319 would look like this:

Code: [Select]

board <- {
  mappernum = 319,
  cpu_rom = {
    size_base = 0x20000, size_max = 0x20000, banksize = 0x8000
  },
  ppu_rom = {
    size_base = 0x10000, size_max = 0x10000, banksize = 0x2000
  },
  cpu_romsize = 0x20000, cpu_banksize = 0x8000,
  ppu_romsize = 0x10000, ppu_banksize = 0x2000,
  ppu_ramfind = false, vram_mirrorfind = false
};

function cpu_dump(d, pagesize, banksize) {
  for (local i = 0; i < pagesize; i += 1) {
    cpu_write(d, 0x6004, (i << 3) | 0x40);
    cpu_read(d, 0x8000, 0x4000);
    cpu_read(d, 0xC000, 0x4000);
  }
]

function ppu_dump(d, pagesize, banksize) {
  for (local i = 0; i < pagesize; i += 1) {
    cpu_write(d, 0x6000, i << 4);
    ppu_read(d, 0x0000, 0x2000);
  }
}
Ask somebody familiar with your dumper to translate that to your dumper's script syntax.

Thank you very much
I will try to ask.
Can you please share the multicart mapper modification? KB46 and 14-in-1 please.
6000-in-1 according to dragon2snow it is a mapper 227.
160000  Similar to mapper 395 and 52
3000 in 1
perhaps similar to mapper 391

These two cards maybe mapper 57, but I havn't the script.

I don't understand --- have you now successfully dumped "130-in-1"/"63-in-1 NJ-01b"/"66-in-1 KD-6130"/"78-in-1 KD-6129" using that mapper 319 script?

158-in-1 and 999-in-1 use the same mapper (428) as "14-in-1 (WL 118-9999999in1)" and "1000000-in-1 (KB46)". Since you have already dumped WL 118 and KB46, you must already have a dumping script for it.
