I really like this program but I have a major gripe about it, and that's the way it outputs the files for the separate tracks using the MD5 hash as the filename.  Any track that has the exact same hash value as a previous track just gets written over the top of the other one, for example with this disc http://redump.org/disc/32549/  So it is kind of self-defeating.

You should change the way the files are named.  Instead of naming them according to a hash value, name them Track 01, Track 02, Track 03, etc etc.  Besides, how is a person going to know which file is which track using this hash value naming method anyway, unless you throw them all at clrmamepro?

Ys Book I & II ( http://redump.org/disc/32091/ ) states that "The first 2 sectors of the 3rd track's pregap are scrambled data sectors."

This is actually wrong, it should be the first 3 sectors, not 2.  I was fixing a clone CD version of this from the Trurip set to match the new database entry here at Redump when I discovered this.  The trurip image was perfect except the checksums for track 3 wouldn't match until I scrambled the first 3 sectors of it instead of just the first 2.  I managed to figure this out comparing the USA version to the Japanese version with a hex editor, the japanese track 3 is correct but is also 1 sector smaller in the pregap than the USA version.  I thought I should bring this to your attention so no one else pulls their hair out trying to get that track right.

So there's 3 scrambled sectors, then zeroes, and then the actual non-zero data starts at offset 376240 (5BDB0).

Hey guys.  I was going over my PS1 collection to check if anything needed to be updated and noticed that some games are no longer on the database here and I was wondering why?

The USA games I noticed missing so far are:

International Track & Field  http://redump.org/disc/6654/
Irritating Stick  http://redump.org/disc/6640/
Jumping Flash! 2 Big Trouble in Little Muu  http://redump.org/disc/6655/

Now the pages just say "Disc with ID "insert_number_here" doesn't exist."

I know they were there before because I collected them and created URL shortcuts to them as soon as they were posted (like I do with all the games).  I don't know what else is missing right now since I don't really have the time to look (I stopped an letter "J").  The current datfile doesn't list them either, but maybe someone has an old datfile and can verify this.

Were they bad dumps?  Or did something go wrong with the database?

The dumps I listed above were posted sometime between April 5 and April 15 of this year AFAIK, if that helps any.

I'll get back when I have time.

About track01-02 (call it low density): you have to move pregap on beginning of track02, so yes those 150 empty sectors are pregap of track02, but you have to cut it from end of track01 and add the same size 0x00 at beginning of track02.

About high density (track03 or more): first you have to be sure that there's only one track (I don't know if Naomi gdroms are only made of 3 tracks as DC ones can be also of more tracks in high density), then high density is always the same size in the sector range 45000-549150.

By the way if you don't have the original to have a correct dump you cannot have nothing useful for Redump project.

Right I understand that.  But there are already 7 comfirmed dumps from Dumpcast, and generally from what I've seen they are spot-on barring the fact that they leave out the pregap on the track02.bin's.   4 of those 7 confirmed dumps are available as CHDs in MAME that can be successfully converted to GDs, and they are the following:

After adding pregap to the 2nd tracks on all of those games, we end up with the following for the 2nd tracks:

So at least you can be somewhat sure that in the future if someone comes along and dumps the NAOMI games your way, they will more than likely match what I just posted.  I also took notes on these games and the other ones that haven't been confirmed yet.  Track01's and Track02's seem to have a consistency on their sizes.

Track01 generally consists of 300 or 450 data sectors (4-6 seconds) for most games.  Only a handful of the games are different.
Track02 is generally 1984 data sectors, and 4 games actually have 1998 data sectors.  Ikaruga is weird because the second track begins where the first one ends, there's no zero data in between.

but anyway, if no one's interested in this info then you can just close the thread.

Gimme a break already.  I was in a hurry yesterday morning when I posted that.  DOS, command line, bah whatever.  If it's in a black n white box on my screen I just call it DOS lol tongue

Akuma, I don't want to cut off your work, but this is the well known method to convert CHD to make them playable on NullDC.
Moreover it's nothing I think Redump care about as the images you can obtain are like DC dumps by dumpcast (no write offset correction, missing pregap for some data tracks).

Instead it will be a great and good thing that some owners of Naomi gdroms will dump them the same way we dump DC gdroms.

I don't want the Dumpcast method though.  See that's what confuses me about GDs is that Dumpcast does them one way and you guys do them the other way.  Also, I haven't seen anything anywhere on how to reverse NAOMI chds to GD-ROMs other than 1 guide that was posted at a few different sites word for word, and it uses bin2iso which doesn't seem to make the right cue sheets at all, because even when I changed the last track to Mode1 instead of audio IsoBuster would get errors.  And that guide was intended just for getting the last track so you could run it in nullDC-Naomi, it didn't cover what I am trying to do, which is obtain the full image from the chds (which I did).

I was taking notes from the images I made and noticed that most of the images had either 300 or 450 sectors of data in Track 1 (sectors 0-299 and 0-449 respectively).

Track 2's seem to have about 1983 or 1984 sectors of data (only 4 images have all zeroes in the first sector of Track 2).  Only the Gundam games are different, with 1998 sectors of data (from sectors 600 to 2597).  All the track 3's are the same size except for CVS 2 2001 because the track is too small, and I read a few other places that it was probably a bad dump.

Also like I said, all the track03.bin's that I made matched the ones that Dumpcast has listed, and comparing notes between the Dreamcast dats from Redump and Dumpcast, there's no difference in the filesizes or checksums for track03.bin's of Dreamcast games.  So I figure the same goes for NAOMI games as well.  The only thing I see with Dumpcast is that they remove the 150 sectors of zero data from the end of Track 1, and add 150 sectors of zero data to the end of Track 2.  When I did it their way, yeah I got perfect NAOMI tosec images, which I DON'T want.  But all in all I do believe I am on the right track here.

For SFZ3 Upper for example:
track 01 sectors 0-299 contain actual data
track 01 sectors 300-449 are all zeroes (Track 02 pregap?)
sector 450 is the first sector of Track 02, but is all zeroes.  sectors 451-2433 contain data.  2434 to 44999 are all zeroes again.
45000 is where Track 03 starts, and it ends at 549149, which is consistent with all of them barring CVS2 2001.
Capcom vs SNK 2000 Pro is setup the exact same way as SFZ3 Upper too.

EDIT-  I'm just going to use the Dreamcast method in the other thread here for adjusting the pregap on the NAOMI images (remove 352800 bytes from the end of Track 01 and add to beginning of Track 02).  It looks like the NAOMI images are just like Dreamcast images in so many ways.  I think this is the only step left and then the images will be correct.  Hopefully like you said RocknRoms someone will dump the NAOMI images like Redump does.  I would be pleasantly surprised if someone did and their dumps match what I end up with from the CHDs.

Looks good I will definitely give this a try. Also anything to help simplify the dumping process for new dumpers I feel is always welcome. Thanks for sharing. smile

I agree, and that was the primary goal - to simplify the dumping process, not just for new dumpers but for everyone hopefully.

Anyway, I updated the program to version 1.1, and added an option for games with 2 data tracks by including the reMove.exe program into it.  The end goal is to hopefully have a nice dumping suite that anyone can use.  I don't generally program stuff but basic DOS is simple enough for me to understand roughly for now.  That's why I make the code available so maybe the more tech savvy gentlemen around here might be able to translate it into something more like a full-fledged GUI like the GoodGUI for Cowering's GoodTools.

Cool!  Thanks a lot.  I wasn't aware of those tools and threads, or that psxtools had other options besides just the FIX option (the readme file doesn't mention any commands other than ones that got removed).  I'll have a look at that stuff n maybe I can make that ps1redumper I posted a little better.:)

I noticed Fighter Maker (http://redump.org/disc/3246/) has a 3 second pregap.  I am assuming that resizing the data track for this game is the same process as that used for a 2 second pregap, and that you just change the command line:

RESIZE -r -352800 "Track 01.bin"


RESIZE -r -529200 "Track 01.bin"

How do you pad the audio track for this game, since "pregap.bin" I found in a Castlevania thread here is only 352800 bytes?

My other question is about PS1 games that have 2 data tracks, like No One Can Stop Mr. Domino (http://redump.org/disc/2823/) and Street Fighter Alpha 3 (http://redump.org/disc/508/).  Is the same process used for dumping the 2nd track as is used for the first track (Extract RAW Data (2352 bytes/block) (*.bin, *.iso))?  And does the 2nd track need to be padded with the pregap.bin file?

I didn't see any other threads asking about this so hopefully I'm not asking something that was already asked before.

Recently I created a program which I call the PS1 Redumper, which is basically a simple GUI/frontend for the resize.com and psxt001z.exe tools.  What I did was I wrote a basic batch file and converted it to an exe file.  I also added a PAD Audio Track option for games containing only a single audio track like King of Fighters 99 and Castlevania Symphony of the Night, and an option for games containing 2 data tracks like Street Fighter Alpha 3.

EDIT - updated to version 1.2!  New IsoBuster options added for even more simplicity in dumping PS1 games!

Basically you have 6 options:

X - EXTRACT Track 01 with IsoBuster
R - RESIZE and FIX data track (Track 01.bin)
P - PAD audio track (Track02.bin)
B - RESIZE and FIX data track (Track 01.bin) and PAD audio track (Track02.bin)
W - EXTRACT Track 01 and Track 02 with IsoBuster
M - MOVE bytes from Track 01.bin to Track 02.bin

See the included readme for more details.

here's a snapshot of the program:

After selecting an option, the program will ask you for the amount of seconds you would like the PREGAP to be, for those rare occassions when the pregap is something other than 2 seconds.  Also when you run the program, it will automatically create the files resize.com, psxt001z.exe, and reMove.exe, and it will delete them upon exiting the program.

This program will also generate PREGAP bin files now, so for example if you choose option 2 and select a 2 second pregap, it will spit out a file named "2secondpregap.bin", and it will then copy that file to the beginning of "Track02.bin", resulting in the final created file "newTrack02.bin".  Same goes for 3 seconds (3secondpregap.bin) and so on and so forth.  I tested this program on some games and it seems to work as I intended it to.  Please check it out for yourselves, and if you like it, feel free to add it to the PSX guide area of the site.  I'm sure it will really help out people since it takes care of manually typing out command lines in DOS.

Here's the link to download it:  ps1redumper_v1.2.rar

If you are interested in the code from the batch file I created to make this program shoot me a PM and I will give it to you.

One other thing, it may be a good idea to include some info in the PSX dumping guide about dumping games that have only one audio track, since dumping these types of games requires a slightly different approach to the types of games that contain multiple audio tracks.  It'll save some headaches for those new to making proper dumps smile

I really admire you guys for the work you have done with this REDUMP project, I have been following this project since the site was originally the PSXDB.com.  I used to provide the link to this site in NFOs back then when I uploaded PS1 games to the net.  I'm considering uploading proper PS1 dumps again via torrent files, and will definitely include the link to this place if I do.  It is unfortunate you do not allow actual games to be posted here otherwise this would be the greatest game site on the net.
