Since then, Windows has gone through several changes, many of which have inadvertently affected the aging LEGO Island code. This is a list of known '''compatibility issues''' running LEGO Island on modern versions of Windows. | ||
== D3DRM.DLL was not found == | |||
'''Affects:''' Windows Vista+ | |||
'''Description:''' LEGO Island was written around an now-obsolete DirectX API called [[Direct3D Retained Mode]]. It was seldom used and quietly dropped in Windows Vista. | |||
<center>[[File:D3drm_error.PNG]]</center> | |||
'''Solution:''' | |||
* Restore Retained Mode manually using either of the following options: | |||
** Acquire the file '''D3DRM.DLL''': | |||
*** The official LEGO Island disc contains an installer for DirectX 5 including D3DRM.DLL. It can be found at <code><CD drive>:\redist\directx\d3drm.dll</code>. | |||
*** Download the most recent version of D3DRM.DLL: [https://legoisland.org/download/d3drm.zip D3DRM.ZIP]. This build is newer than the one on disc (2001 as opposed to 1997) and has generally better compatibility with modern Windows (particularly when using dgVoodoo or if playing in Wine) as well as [https://msdl.microsoft.com/download/symbols/d3drm.pdb/3B7D82D31/d3drm.pdb debug symbols] that are extremely useful for modding. | |||
** Copy '''D3DRM.DLL''' to either of the following locations: | |||
*** The LEGO Island install directory (usually <code>C:\Program Files\LEGO Island</code> or <code>C:\Program Files (x86)\LEGO Island</code>) | |||
*** The Windows system directory (usually <code>C:\Windows\system32</code>) | |||
* Use a version of Windows older than Windows Vista. | |||
== LEGO Island often crashes upon exit == | |||
'''Affects:''' Windows 7+ (earlier versions may be affected too) | |||
'''Description:''' When trying to exit, the game may glitch up and crash. The cause of this is unknown, but is presumably a change in one of the Windows/DirectX APIs that LEGO Island uses. | |||
'''Solutions:''' | |||
* Use an older version of Windows (95/98 are known to not suffer from this bug). | |||

'''Description:''' LEGO Island was written around a very old version of DirectDraw, including a [[Direct3D Retained Mode|retained mode API]] (D3DRM) that is not only unsupported now, it's also been dropped from Windows/DirectX entirely. Many of its DirectDraw function calls are obsolete, deprecated and/or completely abandoned now. There is one specific case, on some XP computers (around the time of Vista-compatible stickers) AUTORUN.EXE, and ISLE.EXE are shown as non-compatible Win32 applications, and will refuse to run (has not been tested with Rebuilder, that might fix it). | |||

* Change to | * Change to one of the software modes (RGB Emulation, MMX Emulation, or - [[#Textures are heavily glitched|if using a version older than Windows 10 1809]] - Ramp Emulation) in the LEGO Island configuration. These use CPU/software rather than GPU/hardware (theoretically slower, but imperceptible on modern PCs), so hardware/DirectX API differences aren't so impactful. | ||
* Use [ | * Use "Direct3D HAL" with [[dgVoodoo]] installed. dgVoodoo wraps several old DirectX API calls to modern DirectX 11 calls, fixing a huge amount of compatibility issues with modern software and hardware. | ||
