How Bleem! or Blini read the Disc ID ?

babylon5 · January 3rd, 2003

Bleemcast does not recognize my original
spanish Metal Gear Solid

Even Bleem! for PC tells me it's not the Metal
Gear Solid.

I've checked the Disc ID returned by Bleem!
and it's different for any MGS CD listed by Blini.

So I thought of patching an ISO of the CD
to change the DiscID and try to fool
Bleem!/Bleemcast.

The problem is I don't know where this DiscID
is stored.

Does anyone knows something about it?

The id code is usually the name of the exe file on the cd, and is specified in system.cnf IIRC. You'd need to open the system.cnf file in notepad and change the file boot = to the new name and rename the file orginally specified there to the different name.

However that said, I can't guarantee that will work. Why can't you just use blini to add the missing entry for your copy of mgs? After all that's what it was written for

That's what I thought first, but that's the product code, not the Disc ID. [i.e., Product Code is SLES_01734, Disc ID is 10 digit: 1059133959]

And my intention is to fool Bleemcast, that has not Blini for it.

I'm trying to fool Bleem! first, just because
I'm supposing both use the same technique to
check the disc.

hi!

Right, this DiscID has nothing to do with region code.

Bleem!s DiscID is like a checksum - it calculate it, from different informations of the CD.
Only Randy (and his team) know which informations it use, atleast I don't know anyone who has reversed how it's calculated.

Blini! has a internal table, with the DiscID's and the region codes, so instead of calculating the DiscID from the cd content it simply check the region code, and search for the related DiscID in this table.

Doesn't Bleemcast! use the region code to identify the game, instead of such a checksum ? As far as i remember there is a bleem!.ini with the region-codes of all versions of the game.

Cu, JNS

Blini has the ability to figure it out the
Disc ID for most discs, when you add a new CD.
(At least the v5 I've tried has it).
But is not working with my Metal Gear Solid,
it reports a different Disc ID than Bleem!

I've made a test editing an ISO of my MGS,
changing the product code to SLES1370 (the one of the first PAL MGS) in the system.cnf,
renaming the bin and editing the MGS1.EXE.

This patched ISO works fine under the emulators,
but Bleemcast does not get it. And Bleem! still reports the same Disc ID as my spanish MGS CD.

The Bleemcast CD is not readable with the PC,
so I don't know what is there...

Thank you, anyway!

I had a go at changing the system.cnf file to fool bleemcast into thinking the game i was trying to run was the right one for the bleemcast disk i was using (i tried to get bleemcast to accept final fantasy 9 instead of gran turismo). I could not get this to work. I assume that if it was that easy then a lot more people would have done this and posted information about it. I guess that bleemcast is a bit more clever than that and looks for other information of the game's cd. As there are a number of different bleemcast disc's, they all may have game specific code in the emulators themselves, i don't think there is a generic psx emulator for the dreamcast, pity since bleemcast proves it is very possible indeed.
