About BINHACK
 

What he does ?

It takes 3 parameters :
_ new LBA value
_ ip.bin name
_ 1st_read.bin name

It rewrites ip.bin (but there's no need to) and changes LBA value in 1st_read.bin by the one you gave. You can do it manually, by looking for "CD001" in your bin file and changing 4 bytes, 8 bytes before.

what do you mean by "there's no need to"? If it is not necessary to modify IP.BIN in order to make a selfboot, why does binhack need it?

I didn't wrote binhack.
In ip.bin, you can find the name of the 1st read file, so I guess it rewrites it if it's incorrect, but it's correct in 99,99% of cases.
But if you want to insert a logo, for example, you'll have to do this AFTER binhacking your files, otherwise, this part will be overwritten.

Thanks for the light.
