Re: Hacked Famicom Cartridge cart - Need info for dump

Of the 4 MiB of the partial dump you sent me, the first 2 MiB are accounted for; the next 1 MiB is what Kazzo sees as open bus ($FF), and the last MiB are the UVEPROM repeated to fill 1 MiB. Unfortunately(?) I only have 16 KiB of the contents of the UVEPROM, and unlike the existing dumps of MK008/M...

Re: Hacked Famicom Cartridge cart - Need info for dump

I quicky cross-referenced the broken dump (the first half of each 32 KiB contained a copy of the second half, i.e. "PRG A14 was kept high during dumping") you'd sent me against everything in GoodNES, and found: * The first 2 MiB are a perfect match for the first 2 MiB of what's called "260-in-1 [p1...

Re: Hacked Famicom Cartridge cart - Need info for dump

I have some difficulty using the PM system (mails stuck in the Outbox). Messages stay in the outbox until the recipient reads them; then they move automatically to "Sent" It seems it did the work! Now I can play games. The ROM size in the ZIP is 2MB. The odd thing here is the cart is 700-in-1 and a...

Re: Hacked Famicom Cartridge cart - Need info for dump

Oh, huh, Nestopia's got some funny code going on with four different variants of what it calles Golden Game 260-in-1, handling up to 4 different sizes of PRG: selector ( prg.Source().Size() == SIZE_1024K ? 0 : prg.Source().Size() == SIZE_2048K ? 1 : prg.Source().Size() == SIZE_3072K ? 2 : 3 ) [...]...

Re: Hacked Famicom Cartridge cart - Need info for dump

Oh, yeah, that's totally plausible. I see part of a menu there. The 4 MiB dump probably won't work in an emulator, but if you zip it up, is it approximately 1.5MiB in size? UH THIS IS ODD. I tried the zipped from and see what I have : a 100-in-1 version ??? The cart is a 700-in-1! I'm really surpri...

In a zip, it's 748Ko. Picture in attachment.

Re: Hacked Famicom Cartridge cart - Need info for dump

I don't see a particularly plausible way that all three ROMs would die at the same time, in the same way. I'd vaguely wonder if the 74'139 is working? Do you have a logic tester / voltmeter / resistor+LED of some sort? If so, you could test whether certain pins are high or low when go to dump it. I...

Re: Hacked Famicom Cartridge cart - Need info for dump

Oh dear. That's a big pile of nothing (hence why it compressed so well) At best, that's the memory region that would correspond to the empty space in the PCB, but ... while the resistor-diode-capacitor was still present, it should have shown the contents of the ROM labeled "MK008". Does the full 4 ...

Re: Hacked Famicom Cartridge cart - Need info for dump

Regarding the resistor, it is that thing? (See attachment) Do I need to just desolder one pin and try to dump? Do I need to desolder the resistor itself and solder something else to keep the conductivity of the circuit? The circuitry there should look something like: M2 --|>|---+-+--- both 74ls174 ...

Re: Hacked Famicom Cartridge cart - Need info for dump

That's definitely "just" mapper an instance of the same hardware that's on 235. The existing dumping scripts should work... as long as the Kazzo is keeping the "clear the registers" pin from resetting things. Did you ever look at the resulting file you got with a hex editor or something? If you hav...

Re: Hacked Famicom Cartridge cart - Need info for dump

I swear I've seen those big silkscreened "MK008" and "MK009" somewhere else recently, but I can't remember where. Since it's a pirate multicart, it'll probably need a custom kazoo script. Given that the only hardware on the board is two 74'174s, a 74'139, and a 74'153, it'll be pretty easy to rever...

Re: Hacked Famicom Cartridge cart - Need info for dump

The real question is what actual games are on it? It's a 700-in-1 special games exactly like the 260-in-1. Does the cartridge has this label? http://mwk1.vot.pl/fw/700in1a.jpg Nope, I don't have the original case. 15 years ago, I remember we changed the case because the original was broken (threw i...
