v1.0 - Ignition on 64-bit Windows 11

Drop-in DirectDraw → Direct3D 11 compatibility layer for Ignition (UDS / Virgin Interactive, 1997).

Runs the original Win95 build on 64-bit Windows 11. No DOSBox, no VM, no compatibility mode. The game executable is not modified (MD5 527bc475783319ecdd8adae1f97f6759).

Install

Copy ddraw.dll and ign_compat.ini from the zip into your Ignition folder, next to Ign_win.exe. Run the game normally. To uninstall, delete them.

dplayx.dll is optional — only needed if the game won't start at all because the DirectPlay Windows feature is missing.

This contains no game data. You need your own copy of Ignition.

Fixes

• black screen (8-bit exclusive-fullscreen DirectDraw)
• silent exit at startup (unimplemented GetDC)
• grey / quarter-width image (32bpp mode, 8bpp pixels)
• crash entering a race (legacy joystick API faulting inside winmmbase.dll)
• 100% CPU on one core (main loop spins and never calls Sleep)

Windowed and borderless fullscreen, aspect/integer scaling, sharp-bilinear filtering.

If fullscreen is stuck small, remove the Windows 640X480 AppCompat shim — see INSTALL.txt.
