Here is a short manual cheating guide.
Search using double (f64)
See value search value works for money, upgrade points, ammo loaded in gun and hp
To hack shop see quantity to buy search quantity to buy then buy as much as you like
Everything is as easy as using cheats except hp which change address often, freeze hp if you really needed that help vs boss, otherwise just use potion. Remember to unfreeze if you change room or the game may crash. The nice thing is every time you change room the game auto save so nothing lost when you crash.
