DC selfboot patch v3.0

[dpaddict]

Ok this is going to sound strange but i binhacked the 1st_read.bin, then i went to hex edit it only to find that there was no instances of the A600 hex values, then i copied the ip.bin to a different folder and binhacked all the other files.
I then compared the two ip.bin's i had and the one in the selfboot folder was different so i used the one i copied to another folder to inject into the iso file.

However when i put the disc in the dreamcast i got the same error, it came upto the 'Now Loading' screen then resets to the menu screen.

Could this be because i used the ip.bin which wasnt used to binhack all the .bin files?

Also ive heard that using a 45000lba would work, however i was wondering how i got a audio.raw file that size for the lba?
I read about it at http://internetconvoy.com/4500.htm however both files there are down.
I searched the forums about this and there is a guide but i couldnt really understand that.
