TL;DR

In 2025, players have confirmed that SimCity 3000, a classic city-building game from the late 1990s, can now be run in native 4K resolution on modern Windows systems through a combination of patches and tweaks, revitalizing the game for contemporary hardware.
The breakthrough was achieved by applying a patched executable provided by GOG.com, which enables widescreen support and removes the need for a CD. Additional modifications include editing configuration files to fix mouse acceleration and installing a Direct3D wrapper to support full 4K resolution and modern graphics acceleration.

The process also fixes issues like missing music and graphical glitches, making the game more playable and visually appealing at 4K resolution.

Background
SimCity 3000, released in 1999, is widely regarded as one of the best entries in the SimCity franchise, praised for its detailed isometric graphics and complex gameplay. Running it on modern systems has historically required workarounds due to compatibility issues, including resolution limits and graphical glitches. Over recent years, community efforts have focused on patching and modding the game to improve compatibility, but achieving native 4K support has remained elusive until now. The recent developments build upon previous patches and community tools, culminating in a method that enables full 4K gameplay.
