To 'romize' PCBs!

[F|end]

Hi, i was just wondering here, wich type of equipment do the people use to transform the data in the PCBs to turn them into roms! Sorry my ignorance but i'll be very pleased to know it!

I don't know how illegal this thread can be so, feel free to remove it if so!


Thks and see ya later!

A ton of high-end logic analizer BS... VERY PRICEY!

Nothing illegal about this thread at all (at least not yet).

Eproms are read with an eprom reader/programmer. There is nothing illegal about it at all. To read an eprom you have to actually HAVE the eprom, and if you have it, then you are allowed to make a back up copy.

Mame uses raw dumps of the data on each chip, named after what the chip is labeled on the boardset, and then the whole mess of files is zipped up (some games have MANY Roms, others only have one or two).

You only need high end stuff for new boards, or weird ones. Old ones will dump just fine with a $60 used programmer. I used to have one a while back.

THks for 'enlighting' me!

But, ow much can a piece like that cost? And what about the cartiges?

LOL something funny: Do a comparison between the Tetris PCB and The Street FIghter 2 PCB! It's like small to huge! LOL

look through the mame boards -- there are some guys on there you can send the boards to and they'll extract them (eventually).

These examples are the simplest cases.

Sometimes they do board level removal of imbedded chips.  This is dangerous because the original board can be damaged.

Sometimes they actually will connect leads to the chips on the board.  Safer but harder... better chance of crossing pins, ect.

Sometimes they can read the leads from other locations on the board.

Sometimes they create a trojan.  What they do is load a program by hand into the memory (RAM) that will read each memory location in ROM and send it out a port to be read by another computer.  This can be tricky since most of these boards don't have outports.  So they might send values out to a LED that they have control on or something similar.  This is usually a last resort because of the time it takes... and the chance of errors... But its is a great way to get around many hardware encryptions (since they are usually unencrypted by the time it gets to the processor)... This is how (I believe... don't know the specifics) the CPS2 boards are now dumped to get the XOR files.

LOL!

This thread is almost becoming a 'how to hack your games' step by step! LOL


I wonder if the newbies are at home trying to make some hacking with their genesis and stuf! LOL


...i'm not!

Here's the guy who dumps most of the stuff for MAME:

He has pictures of the equipment he uses also.

Hey wow, I just thought of all that BS with the digital milennium copyright act and the DVD industry...  (ppl got asses sued for making code to break encryption)
I wonder if this "gets around" the DMCA?  because you haven't broken any encryption at all, you let the original device do it and just grabbed the unencrypted data on the other side.  

Just a bit of idle curiosity.  (very U.S. too - may or may not make any sense to you people in australia and UK etc.)

I'm sure they're not retards.

It's a law that to my knowledge only exists here in the US, and was enacted a year or two ago.  I was trying to be considerate of the people in this forum not from the States.

If you're making a basic rom programmer/dumper, you can make one off of a socket, some 74x299's, some thing to power it (7805/heatsink) and a parellel port connector (then of course some programming).

If you're going to buy one that can dump roms straight off the pcb, it's probly going to cost a bit.

You don't need a 2.5k$ rom programming like The Guru has.

Some one mentioned carts, if you're dumping a cart it works exactly the same, except instead of a socket for a dip chip, you'd use a socket for what ever cart type you're dumping (mcmelectronics sells NES, SNES, and GB pin connectors)

I prefer to leave that with experts!
