Background

The existing Borderlands mod file formats kind of suck, so let's come up with a new one.

Issues with the BLCMM file format

They look like xml, but have completely custom escape logic (see here)
Due to the above, very easy to "corrupt" files if you start getting into edge cases
Not the most human readable
Overly restrictive about what is and isn't allowed to be in a command (to try avoid the above edge cases, though it fails)

In Dismissal of Datatables

A Brief Overview
Problem 1 - Bad Naming
Problem 2 - The same fields can be/is used for completely different things
Problem 3 - Not every field is used
Problem 4 - Not every row is used
Problem 5 - Nothing guarentees a field is used correctly
Using Datatables Correctly

Datatables have a multitude of issues, making them completely unsuitable for data mining, reverse engineering and modding. Rather than using datatables, you should always go back to the source, and extract values (or mod them to new ones) from there.

Debugging Games Running Under Proton

These are the steps I've been following to debug games under proton (or rather debug a mod loaded into the game via dll shadowing). It works ok, it's not amazing, but it's the best I've managed to work out.

To start, use a known good build and just get the game running stably. You don't want to be messing with proton options at the same time.

Once the game runs, add PROTON_DUMP_DEBUG_COMMANDS=1 %command% to your launch args, and run it once. This will create a bunch of files in /tmp/proton_$USER/, which dump the entire proton
