For legitimate DDR mixes, all the mixes have the same boot ROM - a Konami 700A01. With your legitimate upgrade kit, you would remove the old security cassette and plug in a new (and blank) one, and insert the new CD. The game would install to RAM, and at the end write the serial number of your System 573 (well technically the serial number of the Digital I/O board) onto the blue cartridge - this is a one-time write, you cannot wipe or rewrite these cassettes. However, this isn't the case with bootleg mixes...

AFAIK you said that these are better

Bootlegged DDR machines are invariably System 573 Digital-hardware based.

These chips were indeed as you describe... one chip for each mix you want to install. Thus they were single mix modchips, and you could typically recognise them by the fact that the install and game CD would be the same disk (if the original boot ROM is in => force install, if the single mix modchip is in => game mode). Back in the day we thought these chips were needed to bypass the on-board security, when in fact they were quite the opposite.

I didn't understand very well part, if I have to replace each single mix modchip or I have to get a Bootleg singlemix board, but the Bootleg Universal you don't recommend me as I read.
Well, I have the 5th mix installer and game cd, but I only have a 3rdmix single mix modchip (As I understand)
Can I overwrite the data on it, or I don't have to? Because on that modchip is essencial per version.

one that could run a wide variety of different mixes and appeared to be compatible with each other - this is the multimix mod chip - I still own one of these, and it's a shoddy piece of kit that cost me £250 about a year ago. This modchip could be used with any multi-mix modchip bootleg (which includes things like Dancing Stage feat. Disney's Rave), and you could usually recognise them because they came with two CDs - a separate game and install CD.
Well the separate game form is ok.

These are the modchipless bootlegs. In the past year, flawless (and freely distributed - sod giving pirates money that they haven't earned) modchipless bootlegs have been created for:

DanceDance Revolution 3rdMIX (ver.JAPAN)
DanceDance Revolution 3rdMIX (ver.KOREA 2)
DanceDance Revolution 4thMIX PLUS
DanceDance Revolution 5thMIX
DDRMAX ~DanceDance Revolution 6thMIX~
DDRMAX 2 ~DanceDance Revolution 7thMIX~
DanceDance Revolution EXTREME
DanceDance Revolution Solo 2000
Dancing Stage EuroMIX
Dancing Stage EuroMIX 2
Yeah, the 573 will work with any of those mixes, but the main problem is the modchip, am I right?

Quote: Chi
Now, the thing is that if you own a single mix bootlegged-System 573, the modchip will stop you form installing and running any other mix. Thus, these disks will only work if you either have a multimix modchip, or (better still) if you have a System 573 with the original Konami Boot ROM. You can tell this quite easily - it's the only socketed chip inside the 573, and it bears the product number "700A01":
One with original ROM:

One with bootleg modchip/EPROM board:
Which of those you recommend more?

PROTIP: USE THIS CHIP IN YOUR 573 and forget about using unnecessary bootleg modboards. You're onto a winner as long as you can get patched CDs from somewhere else(tm).
edit: The Konami chip works for ALL mixes (including those with the security checks removed).

I'm confident that Chi and anyone that owns a 573 board will echo what I just said.

Indeed. I gave the long, detailed answer of what modchips/modboards are. The tl;dr answer is just as Mercury says: if you don't have one of these legit ROMs, get one, and throw away the modchip.

OK, but you haven't answered my question
let's suppose that this chip is from 3rdmix (like my friend has), then I want to become it to Extreme or 5thmix or 4thmix
can the install disc just overwrite the data that contains the previous 3rdmix and put the new information on it?

No, they are only writeable once, or the legit ones are if that's what you mean. Just use a mix with the I/O checks patched out and never use a security cart again.

so those ones are re-writeable as I understand
btw neodude237, which one is the security cart you're mentioning, the blue T shaped one?

Those are not write-able you do not want those, you do not need those, those are for bootlegged mixes. You need to buy if you don't already have one, the small black chip in Chi's picture. The T-shaped thing is the security cart.

Assuming you have Konami boot ROM:

Yes, if you use an appropriate bootleg install disk (NB: an original Konami game CD won't work) all you need is the CD - no security cassette, no replacing boot ROMs, just the correct CDs.

The Boot ROM (black chip pictured a few times in this thread) does NOT change between 573 mixes, ever - nothing is written to the boot ROM at all, ever. A bunch of rewritable flash rom chips are overwritten every time you install a new mix, but these are built-in.

For legitimate mixes, the blue T-shaped cart (the security cassette) is written to once (and can never be written to again) - but you won't find an unwritten security cassette, so this is irrelevant. For bootleg mixes (of any kind), the blue security cassette is not needed.

IIRC, you are intending to try and run a System 573 board from a TV, not a real cabinet - this means you MUST have a bootleg which also patches out the I/O checks. No bootleg 573 Digital game that patches out the I/O checks requires a modchip.

Your only option is to install a bootleg mix - you need to locate and use one of the mixes that does not require a bootleg EPROM board (as you've pictured), but one that runs on a normal Konami boot ROM.

Question if you will.

There's a little gap in my understanding of the older bootleg modchip thing. Not that I really need to know anymore.
It's just that this machine drove me nuts for the past 3 months. It's for my sanity.Confused
Was there an install disk as well as a game disk for each mix with those bootlegs?

From what I've read and worked on. I think the onboard flashrom got erased or corupted on my DDR.
And what was needed was a reinstall. And I did not know how or had anything to do it.

Tia

Thanks to your help. Next time my boss catches me on internet I can stick this to is face.
My boss thinks that we only waste time on the computer. Old school Sad

Afaik, they were either single or double, depends on the bootleg. (Chi could answer this) If it was single, it was controlled by dipswitches. Your 573 most likely had a bad security cartridge or a busted boot ROM (what you replaced with the legit black chip).

Actually, almost every single mix bootleg I've come across didn't use DIP switch 4, but instead was a single disk that would install if you had a legit Konami ROM in (and loop installing if you didn't switch ROMs), and play if you had the associated single mix bootleg EPROM board installed.

More recently I've seen two disk single mix sets (on eBay), but both CDs were in fact identical! These seems to have appeared when lots of us home users were searching for these rarer multi-mix bootleg EPROM boards a couple of years ago...

That's not to say there weren't single mix bootlegs which used DIP-4 (there are so many different bootleg versions that I'm certain I've only seen a fraction of the number - for all I know they might have existed), but that tends to be a hallmark of the modchipless bootlegs.

chosebine1200: If you had swapped GX700 boards (and tried the one with the modchip), it's more likely that your modchip was broken (as otherwise it probably would have attempted a reinstall - though I can't tell for sure as I don't know your precise bootleg). In any case, it's better to have gotten rid of it - one less thing to go wrong in the future!

The Internet is great for arcade repairing information - the techy boys over at Arcade Otaku (amongst other sites) really know their stuff, especially when it comes to monitors.

He had a bootleg mix, so the security cassette is not used. It is only used for legit setups.

A few years later, there were rumours of a different type of DDR EXTREME - one that did not require any modchip at all. The most famous is a two disk set that works perfectly... except if you try to access the "Game Options" menu which will reboot the machine. These are the modchipless bootlegs. In the past year, flawless (and freely distributed - sod giving pirates money that they haven't earned) modchipless bootlegs have been created for:

DanceDance Revolution 3rdMIX (ver.JAPAN)
DanceDance Revolution 3rdMIX (ver.KOREA 2)
DanceDance Revolution 4thMIX PLUS
DanceDance Revolution 5thMIX
DDRMAX ~DanceDance Revolution 6thMIX~
DDRMAX 2 ~DanceDance Revolution 7thMIX~
DanceDance Revolution EXTREME
DanceDance Revolution Solo 2000
Dancing Stage EuroMIX
Dancing Stage EuroMIX 2


if i might add, i got a little different of mod type, that is only one disk set that work, also perfectly in my cab. need original rom tho.
