Question BleemCast! - Some News

sponsored links

 
just downloaded the following files (before anyone says i know it might be a hoax - and probably is) here is some info on it anyway

FILENAME: bleemcast_betas_(real).zip

Contents of ZIP:

\AUDIO
\audio.zip
\bleemcast betas\
\bleemcast betas\bleemcast betas.txt
\bleemcast betas\BLUE.ZIP
\bleemcast betas\GREEN.ZIP
\bleemcast betas\ORANGE.ZIP
\bleemcast betas\PURPLE.ZIP
\bleemcast betas\YELLOW.ZIP

here is the text included with the file
==========================
This is most of the conversation between myself "Me" and the person I got these from "Betatester"

Of course this are not the real nicks we use, I changed that to hide our identities.

These betas are VERY real. They are not locked down to 1 game. They are betas to test all Playstation games.

Now here is the tricky part, each beta tester was given different color coded Dreamcasts.

The betas has something in the code at will look in the rom on the specified dreamcast. The discs will ONLY work on that machine and no other. Some how this code needs to be removed so that it is usable on any dreamcast.

Only other thing missing is an audio.nra which is the audio track to make the cd selfbootable. It should be the same track this is used in the Echelon Selfboot Kit but in Nero Burning Rom audio format.


[03:49] <Me> what did ya'll have to use to burn it anyways?

[03:50] <Betatester> I've never really looked at how it works, before. It looks like it's cutting the first 37376 bytes off the data part of the image, then appending something (That Rand gave us... Included) to the beginning in it's place

[03:50] <Betatester> Just Nero, and some program that Rand gave us. I think he made it.

[03:50] <Betatester> It looks like all it does is cuts up a binary file, though

[03:51] <Me> ok

[04:30] <Betatester> Well, each one was encoded to only work on that specific DC

[04:30] <Betatester> However, if you mean the burning process, no, it was the same for them all.

[05:16] <Me> i mean different color dc's got different builds

[05:24] <Betatester> Well, I'm really not sure if they were different builds or not. I'm thinking that he might have done some kind of encoding on them, AFTER he did the builds, to make it work on the individual DC's. But, I don't know that for sure. He might have had the encoding done during the build itself, in which case they would be different builds for each

Here is extra info included - BETA Known Protections
================== ==================
- basically what happens is it copies its own data to 0x8c00f??? range
- then decrypts that data using a v.simple algorithm
- a mixture of a key in GR14 and using the XOR instruction

0x8c00f1ec: MOVLL (R2) --> R0
0x8c00f1ee: DT R1 - 1 --> R1; if R1=0, T=1, else T=0
0x8c00f1f0: XOR R0 ^ R13 --> R0
0x8c00f1f2: ADD R0 + R14 --> R0
0x8c00f1f4: XOR R14 ^ R13 --> R14
0x8c00f1f6: SUB R13 - R0 --> R13
0x8c00f1f8: MOVLS R0 --> (R2)

- thats the algorithm
- it decrypts the copied instructions

just wondered what you guys thought - as i said i dont want anyone saying i am an idiot because i believe its true or anyone saying "BLEEMCAST is Uncrackable" - because its not un-crackable its just hard to do - i have posted this incase anyone is interested

hope you guys find it interesting - i aint burnt a copy yet because according to this it wont work on my dreamcast - i might do later
