More hex editing
Before editing your save file don't forget to make a backup in case something goes wrong. Since there is no save editor this will have to do. First, get a hex editing program that actually shows the offset, once you do that save the game you want to edit, preferably a new one at the very start of the game so there is no bad surprises. Here is a list of what you can edit: Vitality: Offset 313, 315, 317, 319 and 31B (char1, char 2, etc.) I recommend putting a value of 20000 on the offsets, which is 4E 20 in hex. Gold: Offset 31E, 320, 322, 324 and 326 (char1, char 2, etc.) Maximum value you can put on the offsets is 255, it seems, so I recommend FF. Stats: Offset 43A to 458 (all chars stats, not sure exactly) I know 63 is 99 and 64 is 100. So probably don't touch the 64s and leave the Cohesion value alone, it has something to do with party alignment. Basically you would be looking to put 63 in all of the offsets considering what I have said.
