Again, this probably outdated, but here's the way to use cheese in any game verison
1. Download RPG maker ace
2. Download version 2.29 (for example I've found one on russian resource (cause I'm russian, witout political cotext, I don't like what's happening now myself, but please, don't bully me for that))
3. Use translation patch on 2.29 version of the game
4. Open Game.rvproj2 from patched dirrectory ("out" folder)
5. In RPG maker press F9 key to open database (screenshot 1, cause I'm not sure how it's called in English)
6. Select "Events" (screeshot 2, again, I'm not sure how it's called)
7. Select "Orb of life drain" (screenshot 3)
8. Copy (Ctrl+A, Ctrl+C, screenshot 4)
9. Open your current game version (step 4)
10. Repeat steps 5, 6, 7
11. Insert it in "Orb of life drain" event in your current version (Ctrl+V, I hope you don't ned a screenshot on that one -_-)
12. Save project (screenshot 5)
13. Enjoy
You can actually redact almost everithyng in it, even create your own character portrait and model, I'm just adding those instructions for those people who wants to skip all this grinding-finding process. For example I've lost my 648hr playthrough due to the hardrive maulfunction and it hurt me bad - finding all the girls and grinding all over again. I know I could do it all over again but sorry, I just don't feel like it's fair.
Thanks for your time, have a great day.
P.S.: I know this is kind of annoying, but I REALLY need those "battle screams" files cause I'm that-one-man-who-uses-them.
