Progress so far - very little.

General search in CE for unknown value, increasing as I grabbed orbs - nothing.

sol is back2back_nomtx_replace.sol
cannot be edited by .sol Editor (too new of flash)
minerva can view the sol, but does not support saving.

The sol has a basic attempt at preventing changes - instead of saying Medpacks = 2, it has Medpacks = -23,25

I have been able to take a new sol, open it in a hex editor, and modify it to -13,25, and the game does show 12 medipacks instead of 2, so it is the correct idea behind it.

Does anyone have a sol editor that actually works anymore? Really don't feel like finding my way through this obscure save format on the hex editor...

I found it easiest to edit the sol with Ragnarok. Using the sol editor, if you put 14608,7292 in medkits you'll get (14609+7292=) 21900. You can do the same for the orbs and so on down the line. Here's how to make the Flamerat have 32235 health and 25375 damage:
