Thanks for the thorough retest, 33lima. That green board is exactly what I was hoping to see.
The black border is nothing to worry about, it's an aspect ratio thing rather than a fault. The fix tells the graphics translator to scale while keeping the correct aspect ratio, and your game is almost certainly still rendering at a 4:3 resolution like 1024x768. Put a 4:3 picture on a 16:9 monitor and you get black bars either side. The reason it's still stuck at 4:3 is that row you spotted on the repair screen. Your settings.cfg is laid out differently from the installs I've seen, so the app deliberately leaves it alone rather than risk mangling it.
The good news is you can sort it from inside the game. Go into the game's own options (takes a while to load) and set the resolution to 1920x1080 at 60Hz, and do the same for the campaign screens if it offers those separately. The game then rewrites its own settings file and the bars should vanish.
On dgVoodooCpl, that control panel edits a default config sitting in your AppData folder unless you point it at the game folder, so what you saw in there isn't what the game is actually using. The game reads the dgVoodoo.conf the fix drops straight into the game folder, and that already has all the recommended settings in it, scaling mode included. That's why the Cpl isn't copied over, there's nothing that needs fiddling with by hand.
If the bars are still there after setting 1920x1080 in the game options, let me know what resolution your monitor runs at and I'll dig further. Thanks again for your patience with all this, your reports have improved this thing more than anything else.
