detailed questions about Segagen

[petran79]

First Merry Christmas to all and I hope the new year will be better than the previous (yeah right...)

then to the topic
After following closely the various guides included in the self-boot files and also in the forums (Segagen/Smashpack problem ) I was unable to make a self-bootable version of the emulator. I had also problems with CDRWIN not yet recognizing my DVD recorder.

the only thing I was able to make was a working version with DSSB final and Pinoy 2001 though no rom folder would appear.

Basically DSSB converted the image in CDI format and I used Alcohol 120. cdrecord has no results.

I notice when I use mkisofs with command 0,11700 the ISO file structure becomes unreadable in ISObuster. Only with 0,0 is it readable. But even after I use Ipins.exe to insert the ip.bin, in Isobuster I see that no image is inserted when the ISO file structure is readable of course.

basically here's the process and questions.

First about ROM conversion. I converted the ROMS to bin. And renamed them so that no space is between letters. Do they have to have a specific name for Segagen to read them? Eg. CASTLEVANIA_BLOODLINES.BIN instead of Castlevania.bin?

Now in the more frustrating process.

using Echelon Smash Pack.

1.binhack manifest.bin, ginreset.bin, mde_us.bin to 11700 with IP.bin as read-only, then 1st_read.bin with ip.bin as no read-only.

is this process correct? Should I hack only ip.bin and 1st_read.bin? Do I have to replace the ip.bin (date 12/02/2001) with another, eg from Nester? do I have to use also a HEX editor and if so convert what?

2. remove ip.bin from CD_root folder.

3. type the command mkisofs -C 0,11700 -V segagen -l -o data.iso CD_ROOT.

Is this correct or should I type 0,0 instead (see problem above).

4. use ipins to insert the newly created ip.bin file in the ISO.

But I see in ISObuster when I use mkiso with 0,0 only (or else it is unreadable )that no ip.bin file is inserted. Should I use bin2boot /nohack instead?

5. finally the recording process. as I said CDRWIN (version 3.9H) doesnt recognize the CD-ROM drive. Is there a way to record to harddisk with CDRWIN? CDrecord records but with no results so far. It Burns the AUdio.raw and then the ISO file but Dreamcast takes me to the OS title screen.

Only with DSSB final was I able to boot Segagen but only if the Ip.bin wasnt removed from the CD_root folder. Is to possible to modify the dssb.bat to burn segagen?

Basically these are the main problems I encountered. I gave up after waisting many CD's.



here's the dssb.bat file. Basically I renamed the NEW folder in CD_ROOT folder

I made a selfboot segagen pack if you want it pm me. Your roms can have any name they want, it dont' matter.

I am also having problems making a selfbootable Segagen disk. I am using the Ultimate Selfboot kit from dcemulation to make the disc. CDRWIN does not recognize my dvd burner either so I am having to use cdrecord. Bucause of that my LBA offset is 11702. I am using the Lemec selfboot patch and reading through some similar threads I found that 1st_read.bin and manifest.bin are supposed to each have 2 occurrences of 5A2E in front of CD001, which are supposed to be hacked to 5C2E for the 11702 offset. One of my problems is that I can find the 2 instances of CD001, but only one instance of 5A2E. So I hex edited what I could find to 5C2E. In the other 2 bins I couldn't find any instances of 5A2E. So, anyway I started up Ultimate selfboot and burnt the CD. The disc boots up properly and I can see all the files, but when I go into the roms folder and try to start a rom, it resets. Does anyone have any ideas?

I finally figured it out after about 100 CDs (I know that sounds a little extreme, but I wanted it that bad). My major problem was that in using cdrecord, it always set the offset to 11702 while obsidian is set to 11700. I tried to use cdrwin, which supposedly would burn audio.raw to 11700, however it wouldn’t recognize my burner. I even followed someone’s advice and use cuttrack to chop audio.raw down so that it would burn to 11700, but no matter how far I trimmed it down to, the offset was still 11702. So next I had to resort to hex editing. In reading some of the threads on this forum the general consensus was to change the 7th and 8th bytes in front of every occurrence of CD001 in the 4 bin files. Supposedly 1st_read.bin and manifest.bin had 2 occurrences of CD001 and the other 2 bins had 1 occurrence each. This was true, except that the 7th and 8th bytes were supposed to be 5A2E and were supposed to be changed to 5C2E. The problems with my files was that ginreset.bin and mde_us.bin had no occurrences of 5A2E and the other 2 bins only had 1 occurrence each of 5A2E. I read on these forums that a few other people have had this problem, and could not find anyone that had a solution to it. So what I finally decided to do was hex edit the 7th and 8th bytes in front of every occurrence of CD001 in those bins, whether or not 5A2E was present. I then used Ultimate Selfboot to create and burn the disc and it finally worked. It doesn’t look like there are that many people still trying to get segagen to work, but if you still are, I hope this helps.

If you want the first track to end at 11700,you need to burn it in sao/dao mode.CDRWIN works by default because it burns in dao by default while cdrecord burns in tao by default.Add -sao for the first track(audio.raw or whatever) for cdrecord 2.x.For cdrecord 1.x it is probably -dao instead of -sao.
