Hi there guys.
How acurate is the NGPC database ? Who did dump those carts ?
I'm redumping my 15 NGPC games, using a Pocket Linker but seems very few of my dumps match current ones in DAT file, no matter how many times i dump them.
All of my dumps are playable on emulators, but as i said, just a few of them match current ones.
I'll try redumping them all again tomorrow on another computer to see if there is something wrong here.
Any ideas to get perfect NGPC dumps?

The NGPC database is simply 0% verified.
When you dump several times, do you remove the cartridge from programmer and re-insert it? Because if you don't, you're likely to redump the same bad dump 1000 times.
Did you also check your dumps in goodngpx, it might recognize different formats...
If you did thought, then your dumps are probably correct and those in the dat or goodngpx are bad.

I think that the pocketlinker dumps the saves part too, check that or clean the dump.

Well, seems i finally got this working correctly, but results are not different than the other day, maybe a couple games that gave me different CRCs now are ok. Seems contacts were a bit dirty.
All contacts cleaned, all carts have been dumped 4 times, pluging and unplugging them from the pocket linker between dumps.
At least, all CRCs for all dumps, matches. Gonna check them against current dumps in database to see if they match or not.
ElBarto, can you ellaborate more on what you said ? How to check for savestates in the dumps and how to fix them ? I've no clue. Thanks.
Ok, to make it shorter, here is a modified SFV generated file with CRCs for all dumps.
CRC - TITLE --> denotes current CRC in DAT file, and rom name.
The rest is the CRC list for my dumps.
DUMP1 CRC1
DUMP2 CRC2
DUMP3 CRC3
DUMP4 CRC4

Are you sure about this? Does is dump saves separately or along with the rom? Do NGPX carts use ROMs or EPROM/FLASH,etc?I think that the pocketlinker dumps the saves part too, check that or clean the dump.
At any rate I'd advice geezup to NEVER edit the dumps, or they won't be good anymore. I'd rather analyse the code myself and find out the difference. But from the looks of it, it's just cowering database is total crap.
@geezup, could you make a scan of a NGP PCB (one game with save support) so we can see if it uses SRAM?

Ok, we got it. ElBarto is right.
Check Dark Arms CRCs with saved game, and initialized. The initialized one, now matches the one in GoodCrap. I'll redump the rest later after initializing them from options menu.

Hummm :s
Seems to be flash memory, so the save is likely flashed into it.
Now the question is: Is initialized rom image identical to factory sealed image?
The only way to know that is to buy some factory sealed carts of course.
For instance I know an initialized FDS disk image is NOT 1:1 identical to factory sealed disk image.

yep... unfortunately i don't have any sealed game
But i guess it could be the same. Disks are always more susceptible to changes than flash memory. Unless there is some data initially in that flash. If it comes blank, there should be no difference.

I don't know anything about NGPx ROMs, but if your specific save data was causing the problem, how is it possible that your first dump matched
Dark Arms - Beast Buster 1999 (JUE) [h1]
according to GoodNGPx? Both dumps had *exactly* same save data?
(This seems to be happening to "Metal Slug - 1st Mission (JUE) [a2]" too)
Also, I would like to know how the dump is being "initialized": is there a clear block of data becoming padded to 00s or FFs after initializing? Could the dump work with such block removed? Can you find the block (if any) in the initially matching dumps? Is it due to them not having user save data?

Something interesting about Metal Slug:

Previous ones were :

Metal Slug - 1s Mission_4.ngp F8B1C5FE
What i changed were the game options: difficulty leves, lives and music
MS doesn't have an initialize option, and "remembers" settings, so they are saved somewhere.
So i would say, all [aX] in GoodNGPx are crap. We can get a ton of different Metal Slug dumps by simply playing around with game options. I would say all games that have the "initialize" option will match factory sealed ones, but not the rest, like Metal Slug (who knows what were the initial options for the game)
Just tried Metal Slug with NeoPop, and keeps the changes i made correctly.
About Dark Arms - Beast Buster 1999 (JUE) [h1] matching my initial dump, it can be caused by choosing the default character name. There is a skull where you can save at the very begining, so, there are many chances that everything was like that
I don't remember. As you see, with the new changes, using my nick for the character name, it doesn't match anymore.See attached pics to see all diffs in both files for Mslug and Dark Arms (note my nik in the saved gamed in this one):

I wouldn't be too sure. I am too lazy to search right now, but I posted somewhere the small byte differences between an initialized "zelda 1" disk (FDS) and a factory sealed disk. The difference is very small but it does exist. Chances are it could happen for NGP too, the only way to tell for sure is thro trial, by dumping factory sealed cartsI would say all games that have the "initialize" option will match factory sealed ones, but not the rest, like Metal Slug (who knows what were the initial options for the game)
, the only dumps that will be sure to be correct are those who don't write back into memory, if any exists.BTW, should we make this public? Maybe some people out there can help on the matter.

I have the dumper (costed 110GBP shipped :O)...
BTW, if you are interested in getting one of those brand new SWCDX2 + Disk Dual, FFE stills sell them
Brand new boxed... works great ! I'm still waiting a parcel with 10 NGPC games i bought from that seller back in Christmas. Luckily i got my cash back from paypal. So beware... after examining their feedback, tons of negatives from foreigners. So i would say it's only secure in the U.S. Has other nicks, so stay away from sellers from Tittusville, Florida.
Same seller: videogameswholesale, gameliquidation, maybe more
I would make it public. Maybe someone is willing to donate some sealed carts ? Or maybe there is someone else out there with the dumper and luckily one of my 15 games, but factory sealed. We have nothing to lose.
