As a KotOR modder whose majority of mods involve editing DLG files, NeoDLG is the best DLG editor to date and it is not even a contest.
Firstly, NeoDLG (and Vriff's other Neo tools) support macOS and Linux, which means users of macOS or Linux (like me) are able to enjoy the software without using a compatibility layer like WINE.
NeoDLG's feature of exporting TSLPatcher/HoloPatcher instructions for dynamic DLG file patching is a real game changer for modding dialogue. In the old way of using DLGEditor to edit a DLG file then using ChangeEdit to generate the TSLPatcher output, if you add new dialogue nodes to a DLG file, the indices of those new nodes are fixed. This means a different mod that also adds new modes to the same DLG file can end up sharing the same dialogue node indices, causing the two mods to conflict.
On the other hand, NeoDLG's patcher instruction export feature makes use of 2DAMEMORY so the indices of new dialogue nodes are not fixed, thus TSLPatcher and HoloPatcher 2.0 (earlier versions of HoloPatcher does not support DLG dynamic patching) can patch DLG files when adding new dialogue new modes in a dynamic matter, which improves compatibility with other mods that patch the same DLG files. Not to mention, NeoDLG exports the patcher instructions faster than ChangeEdit when generating the GFF output.
The KOTOR mod builds are probably the closest thing we'll ever get to a remaster, therefore I consider them a must-have when returning to KOTOR.
However, the modlists are huge, and installing them by hand (let alone without a mod manager) is very tedious - I wasn't even going to bother trying till I came across this plugin. Since Mod Organizer 2 is my mod manager of choice, this plugin was a no-brainer.
And man did it deliver: it downloads, installs and patches every mod on the list in a matter of minutes, kinda like Wabbajack. The "Kotor Dialogue Fixes" mod had an older pinned version that I had to download manually, but everything else ran flawlessly.
The widescreen/resolution mods need to be installed separately, since they involve modifying the .exe and whatnot. I'm running the new KOTOR Modern Restoration Patch which seemed to work better for me than the mod builds setup for widescreen.
I'm several hours in and everything looks great. This plugin must've been an incredible effort, and I can't recommend it enough.
