NFL2k games, need info about fake toc

[SMiTH]

idk i think blowfish.bin is on the official retail gd rom as well
check out the gdi and compare the echelon rip.
from what i remember the files were the same.
maybe check filesize too.

There must be some encryption going on then. That might help explain the amount of time (6 mo.) spent on the releases. You are definitely right in saying this is an 'odd' release. I've never seen anything like this until you pointed it out.

Can we now say your 10 year old streak of not getting useful help is over?

[SMiTH]

one of the other odd releases would be phantasy star online ver2.
it used encryption (.sea file?) and the game bin was not 1st_read it was dp_address.jp, also part of the protection was that the filesize of certain files (.sfd?) needed to be exact or the game would become buggy.
planetweb 3.0 does something similar where it needs the exact filesize of certain files or it becomes buggy. (with image files)
action replay, dc-ie, gameshark had odd protections.
there are plenty of others too.
then there is the ultimate example bleemcast!
it is 2021 and the retails are still being cracked.

When it comes to protection schemes and odd disc layouts - I listen to what @megavolt85 says.

same here.
i respect megavolt, he knows his stuff for sure.
but i think in this case of nfl2k1 he might be incorrect.
there are too many things that don't make sense.
if you are able to get it working with bootdreams, then i will change my mind.
if it works then it will make all of this simple.
but it does not explain how echelon created the selfboot.

*ps i still think the bleem beta colors are different.
not because the hex code is different. (that only means the other colors are encrypted) *compared to cracked blue beta
i still believe they are different because no1 has cracked all the colors and we rely on the creator under an nda and a unknown cracker in 2003.
i want some1 to prove they are the same!
ya tinfoil lol

[megavolt85]

how can you edit lba if file is encrypted?

Why change something that works great?

why would echelon create 2nd session @ 356637 lba?
why would they mirror 2nd session as the first?

you apparently see the data/data image for the first time

here is the reassembled image from echelon, which I just made, and in order for you to have no doubts that I collected it, I changed the volume label and removed IP.BIN and ECHELON_INFO.TXT from the image

[SMiTH]

tell me how to recreate it pls.
my only data/data reference has ever been 45000 lba.

but why give the bootdreams answer?
as you know bootdreams wouldn't work.
i have no idea how you did this.

[megavolt85]

and it boots?

I collected by hand

Code: Select all

mkisofs -C 0,0 -V "NFL2K" -l -x IP.BIN -G ./data/IP.BIN -o NFL2K.iso ./data
cdi4dc NFL2K.iso NFL2K.cdi -d

you can use bootdreams, just be sure to set in the settings that you need the data/data image, the default setting is audio/data
P.S. bootdreams is just a graphical shell that launches mkiso and cdi4dc in the same way

[SMiTH]

mkisofs -C 0,0

wtf? now im lost lol

this goes opposite to any dc iso ive ever made.

thats crazy.

the only isos that i have ever seen at 0 were sdisos.

so how in the hell does this even work?

??????????????

[megavolt85]

-C 0,0 can be omitted, the image will be built under zero LBA even without this option
if you are confused why the image is collected under zero LBA, then this is exactly how DATA / DATA images are created, all data is stored in the first session, only the table of contents of the disk is stored in the second session
