DOJ Black Label ROM Swap Discussion:

[TonK]

Word on the street is that this is close to completion - anyone hear anything?

[yosai]

News travels fast.

Yes, a EPROM can be burnt to upgrade a WL in to a BL PCB. The ddb10.u45 file from the Black Label MAME ROM has been modified to remove the NVRAM checks. The code will be released at some point in the near future. At the moment there is no way to differentiate the substitute ROM from an original BL PCB. Which probably isn't a good thing.

Well, if it were me, I'd get the updated? ROMs for my BL PCB so it wouldn't suicide.

Or buy a WL PCB so I could get it upgraded.

Wonder if the price on a DOJ will go up cause of this?

[Dave_K.]

I sense a facepalm from drboom any minute now.

I hope whoever's doing this changes it in some way to make it very clear what it is, like making one of those version string dots into an exclamation point or something.

BL PCB's have a BL sticker on the chip by the BIOS. That's a start.

If you want to put this into the wild, please add some kind of indication on the region screen.

You can change the year to 2011, add three dots at the end, set the date to todays etc.

Just make it possible to detect...

There is, on the region screen the text is deliberately altered.

i like the hack version warning.i don't have a black label pcb myself but i was anxious to see how it would be handled to keep out people wanting to profit off converting white labels.

I agree. Enough sacrilege has been performed in the after market as it is, what with Progear bootlegs and such.

[MmSadda]

I take it the BL suicide issues will be a non-issue on a converted standard board?

Yup.

[jonny5]

Guess I will be buying DOJ again real soon

How soon until it is available, and if it's not 'off-limits' to ask, who is working on this? This is the first I'm hearing of it. I guess it was bound to happen once the mame dumps were made available.

[kernow]

They wait, eager for news

[drboom]

ha ha ha ha...oh man....

I figured this was on its way, but had no way of telling when. Figures.

Ugh.

[drboom]

oh and...

[jonny5]

I take it you finally found a copy then?

[drboom]

Found a BL pcb? Not yet - though I do have a deal I'm working on. May have to rethink this. Cheaper + no suicide battery = big win.

[jonny5]

Cheaper + no suicide battery = big win.

That was my though as well.

[Vyxx]

So are original BL PCBs gunna drop in price?
Or do you think plan white label ones will rise?

[kernow]

[Skykid]

Lol!

[idc]

Pictures paint a thousand palms.

[austere]

If any of you guys do this, make sure you check the original PCB's PRGROM to see if it's different from the known ones.

[Jockel]

So are original BL PCBs gunna drop in price?

Both. BL will drop a lot, WL will gain a bit.

[bitkid]

So uh, WTB DOJ PCB plz.

But really, if you had an original DOJ PCB couldn't you just put a hacked BL ROM in and hang on to the original ROM for completeness?

That's what is happening. :think:

Putting this hacked rom on an original BL board will erase the NVRAM, suiciding the board, so you wouldn't be able to put the original rom back on without rtw's service. So it doesn't make sense for BL owners to do that.

As for price fluctuations, who the hell cares, you are buying the board to play the game in a cab, not form a retirement plan. Prices will essentially stay the same. BL has been slowly dropping in price over the last few years anyway due to most of them needing to be de-suicided.

This thread is about putting a hacked BL ROM in a WL PCB.

That's not true. The ROM has only been hacked to remove the NVRAM check, it doesn't alter the NVRAM contents.

[PC Engine Fan X!]

This is a fascinating thread regarding the ability to convert such a plain-vanilla DDP-DOJ PCB into a BL variant one. The only thing is it will require getting to the 2nd loop to see what changes were made (compared to the 2nd loop run on a DDP-DOJ WL PCB setup). I had a DDP-DOJ WL PCB up & running at the 2010 CAX show for both days and it was cool to see many folks try it out.

Slighty OT -- Will Cave ever allow DDP-DFK PCB owners the opportunity to get their DFK 1.0 or 1.5 version PCBs upgraded to version 1.51 anytime soon?
