Sorry for the late reply folks. Time flies xD.
It would be a tough code to make, especially if this is for console. An easier solution if you're running an emulator, would be to have a macro/script that makes player 2 auto tech. I think I saw a program like that, on that japanese site with a collection of interesting program. Can't promise anything, but I can try experimenting with emulator, seeing what sort of easy hacks I can do.
Yes, removing damage of lava would be easy. As for removing all of the lava, I've never attempted it, so idk how difficult it would be to do. For blast zones, I'm pretty sure I posted the codes somewhere. If not, I can add them in.
As for booting game with pre-set game settings, it's been done before I even started making codes. I just never added them here, since most people already have the code and I wanted to focus on submitting codes not found by anyone else
. I don't mind answering questions. I enjoy these discussions, because then I know, at least someone else is interested too

I've never done it, but my assumption is that they are just editing a pointer. So think of it as simply changing an ID.
