There are a couple of little tricks to loading up the Tuner Pro defintions so thought I'd make a quick post on the procedure.
You'll have to excuse the "retro" Win XP look n feel. I'm running a Windows virtual machine under macOS and XP does the job without too much bloat.
1. Open a file to edit.
Use File >> Open Bin to open the file to edit.
For nanocom .map file select "All Files" as the file type.
2. Open the XDF
Use XDF >> Select XDF to open the appropriate XDF file.
3. Add Compare Bin
Use Compare >> Load Compare Bins... to load one or more compare bins.
With a compare bin loaded you can use the "Show compare difference" and "Show compare bin data".
Using a random mod to illustrate, select a range of cells and multiply by 1.05
Clicking the "Scales" icon gives "Show compare bin data" - table values from the Compare Bin.
With "Show compare bin data" on, clicking "Show compare difference" shows the difference between the map being edited and the compare bin.
If you find yourself having to load the same base file and xdf every time you start Tuner Pro, go into Tools >> Preferences and under the "Genera"l tab enable the two options to load the last used file at startup.
Footnote
I'm offering what I describe as a "basic" XDF as donor-ware.
These have a bit more detail on tables than Td5MapEditor, have some unit converted to more human friendly representations, and allow direct editing on MAP and Boost limits using the GUI.
The "deal" is anyone who makes a donation will receive an XDF of their choice. How much you donate is entirely up to you.
