Re-dummying CDI files

Hi, I was very curious about the "dummying" part of creating a Dreamcast backup. I just wanted to see if it were possible to dummy a 74 min game to completely fill a 80 min. cdr. I really need your help with this since it is my first time openning image files and creating bootable cds. I have not gotten far, and I am a little lost when I got to the part of dummying and adding in new boot-file.

The file I am practicing with is DoA2LE, which is the only file I could find that is close to 74 mins.(73.3 mins).

This is what I have done so far:
1) I used Cdirip to convert the .cdi file to an .iso file, the LBA 11700.
the only setting used was -pregap.

2) I used Isofix version 1.3 to fix the file and I have three files - fix.iso, boot.bin, and header.iso.

3) Next, I used Isobuster v1.0 to extract the entire game, except for the Dummy data, into a folder called DOA2. (Is this part really needed, because from reading I found out that all data will reorgranized and it will read much slower on a DC)

From looking at all the DummyAdd programs all of them require a .cue file and .bin file. The reason why I didn't convert the .cdi into a .bin is because the game already has a dummy file and I needed to use Isofix to correct the .iso file.

Can it be possible use a .bin image and then remove a dummy and inject a bigger dummy file back into the .bin? After that, convert the .bin to a .iso and use Isofix 1.3? I read that the Bin2boot converter also changes isos into self-booting .cdi format.

Please help me if you can I would really appreciate it.

Thanks.

First of all, dummying is not required !
All my backups work fine with no dummy file.

You might be able to delete the dummy file and then insert a new one using Daemon's tools, but I never tried this.

Otherwise, extract all the files from your image using any method you want (CDMage works fine), then make an empty file with any dummy creator you want ("newfile" works fine) and then, use either Echelon's method or Bin2Boot method.

Where can I find Daemon tools?
