Okay, I'll try that. I just have to finish the hidden ability breeding hack first. If you're fine with combining it, I've already set up a GitHub that we can use:
https://github.com/Touched/DSLN
Just send me your GitHub username and I'll make you a collaborator.
I never bother with IPS or anything, I just use xxd to create a hexdump in text format, so I can use git for version control (GitHub has nice utilities for comparing text). Are you using linux? Or shall I write a utility to do this style of patch? You can look at the GitHub for examples of my autobuild system, so take a look and tell me what you think so we can work out a way that works for both of us. I mainly use Python scripts to automatically assemble and insert everything.
