I'm a little swamped this week and next (stupid summer vacation things messing up my daily routines!) but if you're able to make a disassembly of your rom I'd be willing to try having a go at making my poison messaging work. I still don't know what programs you'd use to do that.
If you're just using the Dynamic Action Patch, I'll look into doing it myself. If you have other changes, though, it'd be best if you did it and put it up on Pastebin or something (if that's legal) so I can grab it.
I figure I can compare it to the original disassembly and my own, and hopefully work out if there's space... *shrug* No guarantees, but its a start.
