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. | ||

'''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. | |||

* Change to a software mode in the LEGO Island configuration (Ramp Emulation, RGB Emulation, MMX Emulation, Direct3D HEL). These use CPU/software rather than GPU/hardware (theoretically slower, but imperceptible on modern PCs), so hardware/DirectX API differences aren't so impactful. | * Change to a software mode in the LEGO Island configuration (Ramp Emulation, RGB Emulation, MMX Emulation, Direct3D HEL).
