I hope someone create a savegame edit fast enough.
There is a savegame editor out already, but from my experience it doesn't work.
Tried on 3 saves, all 3 ended up corrupted by it.
Although I utilize a lot of trainers from this website (and most definitely grateful for it), this game is one of the few I've played where it's relatively easy to edit stuff (using CoSMOS) without any trainer. For example, the addresses for AP/SP in battle are fixed throughout a game session (at least for one generation); you don't have to rescan for new addresses after every battle. Same goes for mostly everything else.
For character stats, PP-modifiable stats (STR, VIT etc.) are mostly within 4 bytes of each other. Addresses for Level, HP, AP, EXP can be found before STR. MOV is also editable, which is found just after the address of LUK iirc.
For items, you can edit the quantity, level (for some types) and even the item itself. All items have the same amount of storage in memory, regardless of type. For quantity, I usually freeze the quantity of the first item slot in the inventory, and manually cycle each item such that all items are placed into that first slot. This will make all items in a category have the same quantity.
By storing dynamic addresses (eg. Agarest.exe+E51524) in the cheat table, and setting some hotkeys, I find that it's almost as painless as firing up a trainer for future play sessions.

Is it possible to post the address of the first "item" in your inventory if it is indeed static? I've been able to successfully edit some of the items that I want more of by selling one and then running a new scan with CoSMOS, but if there is always a static address for the first item in the list I would love to have it to make editing items easier.
