Using the Internet Archive, I was able to find an old copy of the DTD file from 2023 here.

I thought maybe changing the URL in the DAT accordingly would do the trick, like so:

<?xml version="1.0"?>
<!DOCTYPE datafile PUBLIC "-//Logiqx//DTD ROM Management Datafile//EN" "https://web.archive.org/web/20230405091520/http://www.logiqx.com/Dats/datafile.dtd">

...but then I get an error saying:

Next attempt: Download the DTD file and use it locally (put it in the same folder as the DAT):

<?xml version="1.0"?>
<!DOCTYPE datafile PUBLIC "-//Logiqx//DTD ROM Management Datafile//EN" "datafile.dtd">

...and that works!

Hope it's able to help someone.

I have a question in return: can this tool also generate Redump-style CUE sheets if I provide the correct DAT?  So far all I've been able to get it to do is write GDI.  Maybe I am misunderstanding the instructions...

Hoping to get this sorted, at the very least it's a good alternative for verification dumps if you already have a Plextor and a Dreamcast - happy to fill out the existing guide as well http://wiki.redump.org/index.php?title= … ping_Guide

On selecting a .dat file it's trying to connect to www.logiqx.com, and as that no longer seems to exist, the program won't work.

System.Net.WebException: The remote name could not be resolved: 'www.logiqx.com'

Had to use this today - doesn't work going from TOSEC to redump with the new .cue based DATs

if you open the DAT with your editor of choice and replace all instances of ".cue" with ".gdi" it will work again. (ctrl+h is your friend)

or if you're like me an inline sed will do the trick

sed -i 's/.cue/.gdi/g' /path-to-and/name-of-dat.dat

I have noticed a minor bug: if the dirs "dat" or "audio" don't exist, produce an exception when click in the point 3 (Choose dat).

There are other exceptions, like, when you try to run it offline and load the TOSEC dat, it crashes, because it can't load the .dtd file from the url in the dat.

I have noticed a minor bug: if the dirs "dat" or "audio" don't exist, produce an exception when click in the point 3 (Choose dat).

I will continue using the application. If I find some other problem, I'll warn you.

Many thanks for this tool LedZeppelin68 !!!

Thanks for this notice.

Track 4 consists of 0x00h, that's why there are so many matches.

So, i modified util to stop searching after 1st succesful match

Just to say something, I would modify the way to choose the output format (Points 3 and 4).
It is not very clear if it will be created in the Redump format or in the TOSEC format.
Until I have used it a couple of times I have not known how to choose the output format.

Many thanks LedZeppelin68

Edit:
The "Save Log" feature saves the game list, not the log.

Until now I converted these games and compared the files between converted and TOSEC and all is OK !!!:
Sega GT - Homologation Special (Japan)
Shutokou Battle (Japan)
Soukou no Kihei - Space Griffon (Japan)
Space Channel 5 (Japan)
Test Drive Le Mans (USA) (En,Fr,Es)

Thanks LedZeppelin68.
I'm going to try it.

Edit:
2 Suggestions:
Can you generate the gdi ?
Quit the "Complete" for each track and show the progress in the bottom textbox.
Something like "Waiting... Converting Track 1 / x" and when the process has finished show "Completed".
Can you check the game "Shutokou Battle (Jap)" (http://redump.org/disc/5716/): It does not do the conversion.

Many thanks for this app.
If it works well, it is something that I am sure I will use a lot.

now the util shows some progress status
no gdi at the moment, will research it soon

Shutokou Battle (Jap) works for me

Can we trust the Dreamcast dumps sources of TOSEC as a secure bet on preserving the fullset?

TOSEC:
audio tracks not offset corrected

that's why there is several dumps of one game that differs only with one audio track (sonic, shenmue)

BUT

TOSEC dumps works with emulators and gdemu
