This patch will force GTA London to work in 3DFX mode with the VooDoo Banshee map.
Since the patch is designed to correct the operation of the game with the VooDoo Banshee, it is unlikely that it can be of any use now, because no one has been using 3DFX video cards for a long time.
Installation: Extract the contents of the archive into GTAGTADATA and run GTA 3D Patch.exe, there will be a choice of "Y/N" to agree to patching, press "Y" and then enter. Running on modern systems is possible using the DOSbox + Win3.11 assembly, which can be downloaded from here.
