NFSU2 Widescreen Fix: ThirteenAG Setup

ThirteenAG's NFSUnderground2.WidescreenFix corrects display and HUD behavior and provides optional compatibility settings. NoOpticalDriveFix addresses the absence of an optical drive; it is not a SafeDisc or DRM bypass.

Install

Finish the 1.2 install so SPEED2.EXE is the file you think it is.
Download the nfsu2 release from WidescreenFixesPack. Put dinput8.dll and the scripts folder in the game directory.
Read scripts/NFSUnderground2.WidescreenFix.ini from that release. Keep FixHUD enabled; HudAspectRatioConstraint accepts Auto, 16:9, 21:9, or a custom ratio in the current source INI. Resolution controls differ between builds; do not add keys from an older tutorial blindly.
Launch once. If the picture is correct, stop. Do not stack a second "widescreen exe".

When it fails

Issue #1573 reports a black-screen hang with SingleCoreAffinity=1; #1649 reports problems after a Windows 11 24H2 update. These are user reports, not a universal diagnosis. Back up the INI, then try SingleCoreAffinity=0 or a windowed mode separately. See the crash page for the unresolved loading-freeze report.

INI keys you will actually touch
Key	Role
NoOpticalDriveFix	Compatibility for systems without an optical drive; not a SafeDisc bypass
SingleCoreAffinity	Limit CPU affinity; disable as a diagnostic if it causes a hang
FPSLimit	Keep rain and shifts sane
HudAspectRatioConstraint	Constrain HUD layout; FixHUD is the aspect-correction switch

Continue with Steam Deck.

Questions people ask

Which file do I download?

The nfsu2 tag on WidescreenFixesPack. Copy the script folder and dinput8.dll into the game directory next to SPEED2.EXE.

Why is the HUD still oval?

Set HudAspectRatioConstraint in the INI. A 21:9 panel needs that constraint, not only a higher resolution number.

It did nothing. What now?

Confirm you patched Underground 2, not Underground 1, and that another dinput8.dll did not replace the loader.
