If you want to edit it, then you would need to change that it doesn't turn on switch 229 and instead turns on switch 230, then change when switch 229 is required to be on in elf scenes to switch 230 (I think it's only one or two times). Other than that you will want to remove line when he jumps back one tile when talking to succubus leader in a room after attack on village. You might also want to give yourself more days before attack on succubi village so you can recruit allies (mino lady, thane + robot merchant, werewolf, first village mayor, dragon lady(who also is bugged in regards that you can't access map where you recruit her)).
But I would say it's honestly not worth it, it's pretty much over after attack on succubi village and rest of stuff just buggy mess (leader scenes don't work, mino lady scenes also don't work, you get send forward to breeding house for some reason skipping whole how and why you got there part).
It's just better to wait for new version with save before entering succubi village. If you want to see scenes just unlock them all in gallery room.
. I did not do any playtesting and there are probably issues, but here you go anyway:
