I have enormous respect (and a fair amount of adoration) for the people who make unofficial patches for ageing games. With each generation of hardware and each new operating system, we lose a few more games, and these dedicated folks are working hard to keep that number as low as possible.
One of these long-running update projects is SilentPatch, a combination patch for Grand Theft Auto 3, Vice City and San Andreas, three games that share an engine. It updated again just yesterday, and while the change-log isn’t especially huge, some of the tweaks made are quite interesting.
