<r><QUOTE author="diego-rbb-93"><s>[quote=diego-rbb-93]</s>Did you make any new research on this, Led?<e>[/quote]</e></QUOTE>

<br/>
I would continue to research type 2 algo, maybe some statistical analysis will help<br/>
<br/>
for now, all i can offer to save space<br/>
1) for a little amount of ...

<r>I think we must save, what can be saved, and store al possible info<br/>
<br/>
I remade xbox_rnd tool, now it doesn't remove the junk from ISO, but only brutes the seed of first type<br/>
saves it to log, and it works much faster<br/>
<br/>
P.S. drag all <B><s>[b]</s>ISOS<e>[/b]</e></B> on the ...

<r><QUOTE author="Jackal"><s>[quote=Jackal]</s>Ok but my questions about the timestamp? Is there no way to predict the seed?<e>[/quote]</e></QUOTE>

i can say - no<br/>
<br/>
the seed value for second type is 128 bit, which consists of two 64 values:<br/>
1: system time and date (we can reduce this ...

first type seed is only 32bit, 256^4 combinations

second type seed is 128bit, 256^16 combinations, impossible to bruteforce, forever

<r><QUOTE><s>[quote]</s>One doubt, is there any restriction when naming the iso?<br/>
Is it necessary to keep the seed in the name?<br/>
Or could it be kept separate?<e>[/quote]</e></QUOTE>

since we need a bunch of information to restore the padding, seed and SS ranges<br/>
it is useless to store ...

<r>I think "UEFA Champions League 2004-2005 (Europe) (Es,It)" is a late game and uses another padding generator<br/>

LOL, i got it, because xboxregen also needs "ss.txt" and i forgot to add the support, lame i am

<r>one more thing we need is a security sectors ranges, they are unique for every game, and we have to specify it<br/>
<br/>
since redump does have this info, this is not a problem <IMG src="https://forum.redump.info/img/smilies/smile.png"><s>[img]</s><URL url="https://forum.redump.info/img/smilies ...

this is time taken to brute the seed value for "Silent Hill 2 - Inner Fears (Europe) (En,Ja,Fr,De,Es,It).iso"
