Someone help!

[BigLos]

I hope someone out there can help me with this... I want to know how to make a no-mod patch. I can't seem to find any tutorial on how to do so. The no-mod patch, is a patch that brings the TOC under 640MB (re-ripping doesnt seem possible because the 700MB iso is 2GB when extracted and I dont know how to repack it...if you know how to do that, that would help too). This is necessary for no-solder mods. Is there anyone who has had any success in creating one? I've been at this for a while now to no avail, and I'm hoping one of you can help.
