Here is the game save:
Crystals are used to buy skills! Very much needed. Money is to buy gifts for the girls during Gigolo Missions. These are the only two things needed to mod.
I found two offsets for the value of money: 16E5C, 258B9
And I'm unsure about the Crystals offset, but I think it's at: 255B6
(It's the only '47' value by itself; '47' hex = '71' dec)
THESE OFFSETS ARE FOR THE SAVE WITHIN THE CONTAINER (the KID.sav)
I tried modding each, and every time there is a corrupted save message when loading it. I'm guessing there is some checksum or whatnot. I can provide more saves if necessary, and I can test saves when I get a chance.
The game comes out in Japan August 1st, and on the 27th in US and probably elsewhere.
