Going through the motions of *paying* to decap and dump a PIC16C621A Naomi PIC (.hex and .asm attached)

Forums are pretty well protected in the US. In practice, as long as you actually take down things (if a property holder complains,) then you're usually just fine.

The only huge legal disputes I see over forums are usually over "slander" or other unfounded allegations and personal attacks. That, or forum owners who simply refuse to comply with legal demands, and it catches up to them. If your inbox works, and your hosting provider answers email once in a blue moon, you usually have very little to worry about here. DMCA has a Safe Harbor provision for a reason.

EU law I hear is much more easy to lose slander cases. Hopefully that never applies to anyone here... seriously. Those suits are hell.

This is the message on the site now. Fuck that, if I have to pay I ain't apologizing.

Damn.


On a lighter note, I once had a customer comply with a takedown by redirecting the formerly infringing site to hardcore porn. The legal teams were not impressed, but also were left without a leg to stand on, and thus settled it there with no damages.

From the article:

Furthermore, the two must relinquish all emulators and Nintendo games in their possession, and as requested in Nintendo’s original lawsuit filing, the rights to both websites will be transferred to Nintendo as well.

So that's Nintendo's doing.

If I had to guess, once they realized the suit was serious they took the site down and put up the apology, and then once they lost the suit and Nintendo took ownership of the site Nintendo just left it up.
 
US laws. I'm not in the USA. So if a US firm want to sue me, I'll just never travel in the US. No international warrant for such low interest stuffs.
And it's very clear that we share tools to repair our own gams, so no problem there.
 
Time for a necrobump! I came back from chilling with @fsckewe for the weekend and I had a Lindbergh - The House Of The Dead 4 disc in my mailbox. This one has a PIC16F648a, so I thought that was worth noting. I'll try to get it sent off as soon as I can to "go through the motions", as it were.

sounds cool. but, are you aware of HotD4 PIC is dumped already, at least 317-0427-COM ?

Sure... just like the Naomi PIC had already been dumped. There has of course been quite a bit of controversy over how *accurate* the current information is, I'm simply going through the motions.This will allow us something to compare against for Lindy, just as we now have for Naomi.

For some reason I have these two attached files sitting in my TODO folder. The last thing I recall doing was:
srec_cat Lindy.bin -Binary -o Lindy.hex -Intel, and then running it through PIDDisam v1.6

Are you aware of a commented version of the .asm? I can't say I've looked anywhere. Likewise I can't even say I'm aware of anyone *attempting* to describe the differences between the Naomi PIC usage (if there is one). After a quick glance of course I can see what MAME source has to offer.

For Lindy:
https://github.com/mamedev/mame/blob/master/src/mame/drivers/lindbergh.cpp#L53

For Naomi:
https://github.com/mamedev/mame/blob/master/src/mame/machine/naomim4.cpp#L15

only basic principle is similar: there is static code part (same for all PIC keys), and the data part where is each game specific key,ID,etc.
everything else is totally different.

right, its enough to know:

The PIC includes an AES-CBC engine and has as data an IV, a key,
some game-specific identification information, and two pre and
post-whitening values. Everything but the key is dumpable through
commands, but the key seems well-protected. It's not realistic to
decrypt very large amounts of data through it though, the bandwidth
would be way too low.

this means there is no way to dump it in software => someone paid money for decap and dumping each of iirc 10 Lindbergh PICs mentioned in MAME sources.
but yes, you may redump them, if you think dumps in MAME is somehow bad or incorrect.

however, if 2 PIC dumps from 2 different games match in static code part - I'd say it is safe enough to assume they are good, because there is quite little chance to get bad/wrong dumped bytes in game-specific data area only.

Only problem I have noticed is people unable to understand how to correctly set config bits with their chip programmers. Provenance of the pic dumps has never been in question.

Even last week, 4 more lindbergh pic dumps were submitted to mame (not added to source yet), guess what the code is static with keys changed, just as MetalliC has mentioned.

But feel free to have your pics redumped, whatever your reasoning is lol
