Just thought I'd share these tables I made for anyone that is interested. If DrummerIX wants to add them to his table, he certainly has my permission to do so, but it doesn't really matter to me. I'm just providing them here in the hope that someone else will find them useful.
The first is an inventory manager script. When you run it, it creates cheat table entries for every inventory item you currently possess, sorted by category, allowing you to easily modify/freeze their quantities. If you click a category's checkbox, it freezes the values for all items in that category. Be aware that if you get a new item that you didn't have when you previously ran the script, you will need to run the script again to refresh your inventory list. Another thing to be aware of is that the game removes an item from your inventory once its quantity reaches 0... If that happens, modifying the value in your address list won't make the item show up in your inventory list again. Making this would not have been possible without the item id/name list provided by DrummerIX, so I thank him for all his hard work!
The second is a "Turbo Movement/Run Speed" script that allows you to set a custom movement/running speed value. This was a tricky one... and it relies on pointer values which likely makes it version dependent (4.0.0 Steam). After lots of testing and revisions, I believe it works across all areas/cities/overworld/caves/etc and with all characters/character-slots. There is no single pointer that is used for the "currently selected character" movement speed value and the code that read/writes this value also reads/writes the value for all characters/npcs/enemies/etc, so it was quite a pain in the ass to get this working. You will notice that all of the characters in your group also move at turbo speed (which isn't really a problem as far as I'm concerned), but all the other characters/npcs/enemies should move at normal speeds (you may see an exception to this once in a blue moon, but it is exceedingly rare). By default, 'F8' enables turbo movement speed and 'F7' disables it. You can change the movement speed by modifying the entry labeled 'DesiredMovementSpeed'. I have it set to '15' by default, which is a little over twice the default running speed, but you can change it to whatever you want. If you want to modify the hotkeys, they are assigned under the entry labeled 'Movement Speed Pointers (Modify Hotkeys on this Entry)'.
If you have any problems, let me know. Have fun!
