The three .zip need a new "dadjd.05" ;) (size 3 145 728 ^^)
I have cut it, and the first 512K is good for the 1st and 3rd release (not tested at this time the 2nd release)

Thanks for your work :D

Actually, no the files on each zip are the correct ones for the set.

This game encrypted size is 1.5MB (three chips) so 05 actually one of the encrypted files so it's a unique 05 file for each one of the three revisions. :awe:

Erf sorry for my poor english i restart :lol: :lol:

In ddtodjdl.zip, ddtodjr1dl.zip and ddtodjr2.zip all other files have the good size (512K), but "dadjd.05" for each zip have a size too high (3mo).

For ddtodjdl.zip, i have cut in 512K and the first part is good.
dadjd.05C CRC 0A10C468

For ddtodjr2dl.zip, i have cut in 512K and the first part is good.
dadjd.05A CRC 54AB2A86

I Ask this just if other user don't know how to cut a file ;)
The CRC are matching your 512k files ?

Thanks :)

oh wow. That's because I work with a 4MB file, which I then cut on 512KB chunks when making the final file (on hex editor).

I forgot to cut the tail off. Will check and fix. :awe:


Edit: ok I fixed it. Thanks friend. :awe:

Hi guys and thank you for the good work.

I used the decrypted roms from the site to try to revive my green vampire savior.

Both euro on Japanese release failed to revive the board.
I reprogrammed the 8 eproms :
First i tried Japan version : 3~10 Japanese decrypted from the site -> no boot
Then i tried Euro version : 3+4 euro decrypted from the site + 5~10 from original euro rom -> no boot

In the end i replaced 3+4 with phoenix code, keeping the previous 5~10 from original euro rom -> it works, but phoenix edition

Thank you again for the amazing work you've done.

Just wanted to report in that D&D: Tower of Doom (USA) doesn't work on real USA hardware. I tried both the version from the Avalanche website, and the multi version split up into proper 512K files. Just end up with the standard screen you get when a game has suicided. I know the board works correctly, I can flash the EEPROMs for the Phoenix version of the game, and it fires right up. Unfortunately, I believe I need the original USA version to enable free play. I'm an actual arcade operator, and need the free play feature to put the game into a barcade setting. I'm sure this isn't high on your priority list, but I have the setup and burning tools to test out any fixes you might try.

Thank you again for your work on this project.

All regions of Vampire Savior have been bugfixed. Released just now, updated files available at http://cps2.avalaunch.net/.

For your reference, only ROM 03 has been changed compared to the previous revision. Please test. :)

Does someone has older or other decrypted Ultimate Ecology ROMs than the ones from the cps2.avalaunch?

I tried to get my dead Ultimate Ecology fixed, but with the ROMs from the site it won't work :(

No, version (date that appears on power on) of the GAME, not the board code. :)

What is written on the stickers could also be of help. This game is one of the cases that ALL EPROMS change between revisions.

Hm I thought the same, but since the game is dead I cannot boot it nor see the revision number :(

On the ROM labels "UECJ" is mentioned.
Game serial number is 020241614

Can you take a picture of the program roms? We can sometimes tell the revision by the letters sometimes placed on the program rom labels.

You have to reprogram all four chips at same time using the four files from the archive. Unlike other games which have just chip 03 or 03 and 04 encrypted, this one has the whole program encrypted.

I actually did this :)

I talked with idc a week ago and he said that the actual ROMs on the site may have an issue.
There should be an older version, which works.
Is this version still available?
If yes, I would like to try that.

I just went to the avalaunch site, downloaded the file uecologydl.zip from there, compared against the uecology set used with Darksoft's CPS2 multi and it's exactly the same data.

Indeed, the file has problems but here's the fix:

At position 0x1F4A change value 0xFF for 0xBF. That will prevent a memory clear routine which executes during display of the regional usage rules screen from writing zeroes to one of the sprite control registers (I suspect that causes the sprite hardware to stop asserting the /DTACK pin on the CPU, causing a freeze).

I will update the roms at the site now, as well.

Edit:

File repaired. On a sidenote I had this file working since 2016, I have no idea how or why the file in the site was outdated patching wise. I am really sorry about this.
