There are many no-intro patches out there. But many do not take you to the menu directly, and in place of the R* logos, only black screens are visible instead, taking the same delay to load the menu.
This mod just replaces a simple .dat file and does'nt show ANY screens or annoying delays at all.
The mod has been tested on GTA IV patches 1.0.3 and 1.0.4 but should work find on all patches.
