Posted By: Just Desserts Nuon dumps? - 08/01/15 11:24 PM
It's come to my attention via reading a datasheet that the Aries 3 processor, of Nuon "fame", has an ALU instruction called "butt". I kid you not. Therefore, it is now my obligation to make a driver for the system at some point.

Interestingly enough, the Nuon platform doesn't appear to have a separate GPU. The impression I get from the datasheet is that the Aries 3 is designed with 3D in mind via software rendering, though I might be wrong.

At any rate, what I'd like to know is if there are any dumps of the boot ROM(s) from any Nuon players kicking around, and if there are any dumps of game discs as well. PM me if you have a line on either, though boot ROMs are more useful in the short term.
Posted By: ssj Re: Nuon dumps? - 08/02/15 12:28 AM
Game (released ones) discs have all been dumped except Next Tetris and Crayon Shin-Chan.

Not sure about the boot ROMs though, but I don't think they have ever been dumped.
There's an emulator named Nuance that emulates the system to some extent (albeit very slowly), but afaik it does that at HLE and uses a replacement bios. Sadly the emulator author passed away several years ago.

Never seen Iron Soldier 3 image in the wild, only demo. However, both Iron Soldier 3 and Next Tetris are mentioned in the Nuance compatibility list, so they were dumped but maybe hoarded. Also, I've never seen a dump of Spring 2000 Interactive Sampler, which was bundled with one of the players.
There are also 4 movie DVDs exist, which have additional menus and features for NUON players.

Are you aware MAME doesn't support DVDs yet? smile IIRC, the format isn't even properly supported in chdman.

News to me. We've got dozens of DVDs in MAME. In CHDs.
Posted By: Vas Crabb Re: Nuon dumps? - 08/02/15 02:00 AM
Data DVD is supported - we have a number of FMV AV mahjong DVD images courtesy of AeroCityMayor. DVD is a relatively simple linear sector-based format most of the time unless you're doing weird shit like packet writing or custom scrambling a la GC/Wii. (Yes, we are missing the key area, the BCA, and the servo data in the "wobble".)

Yes, but aren't they treated the same way as HDDs instead of the proper format support?

I have dumps for both IS3 and a Toshiba 2000 Sampler (not sure if that's what you are referring to), I never checked if they were the real thing or not to be honest. I guess I could try booting them on Nuance and see.

I know a few members at nuon-dome own Next Tetris, I'm not sure if they are ok with asking for dumps on their forums though, but might be the best bet to get it dumped considering the rarity of the game. Shin-Chan will be much worse considered it was only released in Korea.

For all intents and purposes they are HDDs. There's no such thing as alternate track types or sector formats, and DVD-Video is still just a bunch of sectors in a UDF filesystem after you decrypt it.

"Proper" format support on the scale of CDs is neither possible nor necessary.
Posted By: ssj Re: Nuon dumps? - 08/02/15 10:38 PM
A guy owning that Spring 2000 disc is willing to dump it:
http://www.thehelper.net/threads/fa-a-few-nuon-items.163416/

I don't think this is the one I have since I see this is a Samsung disc and the one I have seems to have come with a Toshiba player.

Anyone knows how to dump these properly? Can we just extract user data with isobuster or do they require something special (as in they have any kind of protection)? Seems the guy owning the disc is also unsure.

Yes, but HDD images are packed and used "as is", afaik, but for DVDs the typical images are 2048 bytes/sector, while technically dvds are 2418 bytes/sector (4836 bytes/sector concocted), so the missing data should be generated on the fly similar to CDs (like lead-in) or during the iso=>chd conversion process (or the proper RAW dumps should be used). Precise emulation will need some of these sectors, since they are used for certain protections.

In case Tafoid is reading this, I have received a private message informing me that there are no "boot ROM" dumps, but firmware dumps exist. In this case, I would like to know about these firmware dumps, because they're basically the same thing as a boot ROM. I would imagine that the Nuon systems would boot up from their firmware, y'know?
Posted By: LoganB Re: Nuon dumps? - 08/03/15 06:19 AM
I posted this in the shoutbox, but has since been lost in the scroll: There's developer firmware dumps in the SDK, as well as flashing tools and a list of all the firmware revisions at the time including some interesting bugs. The first revision was limited to the first 1000 units, for example. Not sure I can link it here.

That's the only firmware file I'm aware of, it seems to be some sort of updater program rather than the raw image though so it would take some work to extract.

The DVD-N505 has an OTP EPROM "AMIC A278308-90", I was able to dump it with the settings for "AMIC A27020". I don't know if the dump settings messed it up or if it is encrypted, please see for yourself: http://s000.tinyupload.com/?file_id=81603409329673969598

When you run the DVD-N501 firmware update disc it complains that this isn't a N501. As it is an OTP EPROM I don't see how it could update it anyways, maybe the N501 has a diffent firmware chip.

Thanks for the dump. It's a strange ROM type so it's maybe bad? I doubt it's encrypted and there's normally some kind of plain text readable either directly or with a bit-swap with the manufacturer's name or a date or version number.
Since there's none of that it could be bad.
To figure it out will require tracing the PCB.

Regardless, even if it's good, the NUON dump is incomplete.
There's also an Atmel AT49BV1614 smd flash ROM in the lower left corner of the PCB.
you'll need to dump it before we could add emulation or a basic skeleton driver to MAME.
or send it to someone who can dump it and guarantee it'll work afterwards (i.e. me ;-)
Posted By: rosewood Re: Nuon dumps? - 10/27/15 06:09 PM
Traces of plain text or dates was the first thing I was looking for too. But the size is ok and there are some repeating patterns, so I came to the conclusion that it's not just a bunch of garbage but encrypted, or something is missing.
I noticed that all the chips are grouped together by naming. The A278308-90 is called "MIC2" and the TMP91C219F next to it is "MIC1". The whole NUON part is NICx, e.g. the Aries-3 being "NIC1" and the Atmel flash "NIC11". There is also VICx, PWICx, RICx, SICx...

Unfortunately my programmer doesn't accept TSOP48 Atmel chips, so I guess it's best to send it to you. What do you need, just the two chips or something else from the PCB?

Yep, I gathered as much. I assume the Toshiba one is the same way, but I don't know of anyone who analyzed its updater yet.

According to LoganB earlier in the thread, the SDK comes with "developer firmware dumps" so that's something to work off of at least until the flash chip can be dumped.

I believe he's referring to NUON_Tech_Data\Offical SDK\bin\NUON\aries-dvd-dev.bin and aries-dvd-dev-pal.bin inside the file incog just linked. Dunno for sure tho.

[EDIT] incog's right, it's probably the .cof files.

[EDIT] there's also .zcof files in there, which I'd expect are compressed cof in some way. The flash batch file in there loads the aries-dvd-dev.bin and then a bunch of zcof's.

This class provides an interface to emulate the Atmel AT49BV162A/163A flash memory on the Nuon with enough functionality that the Samsung BIOS update program can be run on the emulator to dump the Samsung N501 BIOS to a file.

Well, they're flash updates for the devkit and I think a reference player, they're mapped at 0xf0000000 and they really look like neon mpe0/3 code. Enjoy that shit.

Noticed some traffic on my page and came back to this thread smile

Yes, I'm still offering to help with this. I own 2 DVD-N504 players and could run some tools/tests on them or even ship one of the mainboard to a dumper.
In 2015 I discussed it with Guru, but there wasn't much value at that time:

Quote

I found the NUON is partially documented here....
http://console5.com/wiki/DVD-N501
there are a few nasty chips probably containing ROM.
particularly the TMP91C219F (MIC1)
others like SIC1, NIC1, VIC1 etc are custom chips/DSPs etc
I personally think it's a waste of time and money for you to get it dumped.
I doubt it'll ever work in an emulator because of all the other custom chips and missing microcontroller rom (MIC1) and that DSP (SIC1)
Posted By: R. Belmont Re: Nuon dumps? - 02/20/18 06:45 PM
We know pretty much all of that is not correct now. The TMP91C219F has external ROM so the firmware can be upgraded, the NIC1 is the Nuon CPU with no internal ROM, SIC1 isn't programmable, it's the DVD controller, and VIC1 is an off-the-shelf NTSC/PAL video encoder.

I actually tried that some time ago with a chinese reader and SDK. Couldn't go past the protection though (can't find the source/documentation anymore).

If you're interested in getting it dumped these days it would probably make more sense to contact somebody from The Dumping Union rather than Guru, because Guru isn't really working with the team much these days.

There's a boot rom in the Nuon actually. Looks like we probably can live without though. As far as I can tell, it copies somehting like 128 bytes of the flash to internal ram (e.g. 0xf0000000 to 0x20300000) then jumps to it. Nothing spectacular :-)

OG.

rosewood, do you happen to own any Nuon games? Next Tetris and the hyper rare crayon shin-chan games are still undumped. There are seems to be 2 different versions of Iron Soldier 3 one labeled as demo and the one not, but I'm not certain if there is any actual difference between the 2 of them.

Can't help you with these. IIRC, The Next Tetris is on the dumped Toshiba Sampler.

checksums matched on these, they are the same

Interesting, didn't know the game was included on that disc. Either way a dump of the actual disc is still needed.

Are you 100% sure that both discs were dumped? What sources are you referring to? The Trurip demo vs the other not marked as a demo from that old Nuon set that's been available for years? My doubt is to be sure to which disc that one refers to.

one set had it in marked as the demo, another set had it in marked as the full game, both checksums matched. meaning we could either have the demo or the full game in the softlist I have. I would love you on board w/ the undumped wiki ssj, were starting to add consoles/computers and their undumped games. https://mamedev.emulab.it/undumped/index.php?title=Main_Page make an acct and i'll let it thru

I tried making an account, but seems that some sort of personal biography is required don't have the time or interest to think of something to write there.

leave it blank, or fill it with rubbish, it's not required
