First you need a hex editor, not a text editor. xxd on linux will get you started but you might want something a little more user friendly.
Then look for a label for a value you know, xxd and other hex editors will show ascii text on the side. Hopefully you’ll be able to identify the value (in hexadecimal, probably 4 bytes but could be 1, 2, or 8 as well) somewhere before or after the label. You might have to get familiar with endianness, two’s compliment, and binary floating point before the numbers make sense.
Once you know how to read a value after a label you’ll need to find some label for the information you don’t know. If it isn’t displayed in the program it might not have a super readable label.
Most people don’t run into any issues with mods online. If you’re constantly running into “asshole” authority figures in online communities it might be you…
It’s primarily private insurance (at least in the US) that drives that. The doctor can prescribe something and then a “doctor” who works for the insurance company can take a 10 second look at it and deny it outright in favor of a more profitable treatment.
I have to believe an experienced holodeck user would be able to detect some of the telltale signs pretty easily. Like replicated food, if you see it enough you probably notice “holodeck vase #5” showing up scattered around the background of scenes as clutter. Or even minor visual distortions where it switches from 3d to the false horizon.
