However, it was discovered that a more recent version of D3DRM.DLL was released in 2001 with Windows XP and also has PDB symbols available, mitigating this entirely. A digitized book from the era was also discovered documenting most of Retained Mode's API. | ||
In many ways, Retained Mode is likely the culprit in many of LEGO Island's [[Compatibility Issues|compatibility issues]] with modern systems. Since Microsoft has dropped any and all support for Retained Mode, it's possible the game's codebase may have aged better had it been written for Immediate Mode instead. | In many ways, Retained Mode is likely the culprit in many of LEGO Island's [[Compatibility Issues|compatibility issues]] with modern systems.
