The game scrambles the memory around to scuttle any attempts to hack the memory. It's a little frustrating. I thought I'd found the right memory section and edited it. The right numbers showed up but reverted to the original numbers. Had to search further and edit more.
Jackbig's suggestion is a great way to circumvent most of this. Install the 2007 version, create a character, use the 2007 trainer for most of the stuff, and save.
One thing I would also add as another way to get god-like: use the Resurrection mod (Google it) and Reanimator on the 2007 version to edit a specific item (sword, gun, ring, etc) to be completely OP. You can also set the values on commonly dropped items to be worth 10-20x the cash and reap the cash from those. Save and open the save in HG:L 2018. Profit.
Just some random thoughts.
