Hacking Anyway to create a patch file

[illinialex24]

For a basic example, I wanted to change the hex values of something, lets say an ISO, to 30 (so the text is 0). This should autoboot it and I know there is a program that does just that.

But lets say I wanted to change a certain line to a certain value, how could I create something like that...

I'm wondering why because I've been extperimenting with cIOScorp and if you burn all your games to IOS1XX where XX is the normal IOS, your in the clear essentially. Have a special IOS slot for the MPT version of the IOS (think its 55) and then you would burn MPT to that and your all set. This way, there are no conflicts with normal stuff. Just thinking... I've been testing it out and it shouldnt take much room because almost everything is a shared file, the DIP module is very small.
