the mana cheat you included doesn't seem to do anything? even with the cheat on, when i do spells my mana just goes down as usual, and once i reach zero it tells me i don't have enough mana to do any spells. the energy cheat seems to work fine though.
and the quantity 90 cheat works very curiously. it does actually make everything in your inventory 90, but that includes things you wouldn't really need 90 of like your tools and clothes you've bought. and i've also noticed that if you drop an item (tried to do this with some shoes), it immediately fills the entire rest of your unused inventory slots with 90 of that item over and over, since i guess the game wants to pick up items you've dropped when you're standing near them lol
